961d1e847c linux: kernel config for extended BPF support
- Enable BPF_SYSCALL and BPF_EVENTS
- Build modules for NET_CLS_BPF and NET_ACT_BPF

With these config options we can leverage the full potential of BPF for
tracing and instrumenting Linux systems, for example using
libraries/tools like those provided by the bcc project.

48f51f1185 linux: Compress kernel modules
This reduces the kernel package from 185 to 62 MiB, for a neglible
boot time cost.

1792ca5810 Increasing mmc possible partitions from 8 to 32.

on eMMC (Android+Win10 dualboot).

e4b4e9b986 linux: Make Unix domain sockets builtin
This hopefully fixes intermittent initrd failures where udevd cannot
create a Unix domain socket:

  machine# running udev...
  machine# error getting socket: Address family not supported by protocol
  machine# error initializing udev control socket
  machine# error getting socket: Address family not supported by protocol

The "unix" kernel module is supposed to be loaded automatically, and
clearly that works most of the time, but maybe there is a race
somewhere. In any case, no sane person would run a kernel without Unix
domain sockets, so we may as well make it builtin.

a7157fa2f0 Remove firmware loader fallback.
Systemd dropped support in 207 (would be nice if configure failed with a bad flag),
so all this does is add an annoying delay if firmware can't be found by the kernel

82d0acaf37 kernel-config: Explicitly enable NAMESPACES
Namespace support is required by the `unshare` tool used in
`nixos-install`. It's enabled by the x86 defconfig, but not by
e.g. multi_v7_defconfig. So enable it here so that `nixos-install`
can work on ARM.

KVM_COMPAT apparently enables 32-bit compability syscalls for KVM, and
as such can be enabled only on a 64-bit system.

6be70d17c0 kernel-config: Enable IKCONFIG so ARM gets /proc/config.gz
IKCONFIG must be enabled so IKCONFIG_PROC can be set. On x86 IKCONFIG
gets implicitly enabled by kernelAutoModules in platforms.nix. But ARM
doesn't use kernelAutoModules, so IKCONFIG_PROC won't get enabled
without this patch.

9c2f2bc893 kernel-config: Enable FB_VESA and FRAMEBUFFER_CONSOLE
Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.

Other distros have similar defaults, at least on Arch:
    CONFIG_FB_VESA=y
    CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
    CONFIG_FB_VESA=m
    CONFIG_FRAMEBUFFER_CONSOLE=y

Fixes #8139
