linux-hardened-config: various fixups
...
Note
- the kernel config parser ignores "# foo is unset" comments so they
have no effect; disabling kernel modules would break *everything* and so
is ill-suited for a general-purpose kernel anyway --- the hardened nixos
profile provides a more flexible solution
- removed some overlap with the common config (SECCOMP is *required* by systemd;
YAMA is enabled by default).
- MODIFY_LDT_SYSCALL is guarded by EXPERT on vanilla so setting it to y breaks
the build; fix by making it optional
- restored some original comments which I feel are clearer

linux_hardened: enable structleak plugin
...
A port of the PaX structleak plugin. Note that this version of structleak
seems to cover less ground than the PaX original (only marked structs are
zeroed). [1]

The rationale for this is to have a place to enable hardening features
that are either too invasive or that may be speculative/yet proven to be
worthwhile for general-purpose kernels.
