Fix the following build failure:

```
In 4.1, the build system changed, and it now wants to execute ld like this:
ld -r -o util/scripting-engines/libperf-in.o util/scripting-engines/trace-event-perl.o util/scripting-engines/trace-event-python.o
The actual problem seems to be that `buildInputs = [elfutils ...]`
causes 'ld' to point to elfutils in PATH instead of the usual binutils.
So remove elfutils from buildInputs and set NIX_CFLAGS_* manually. This
is a slight hack, but there is some precedent:
0761f81da7/pkgs/tools/package-management/rpm/default.nix (L13)Fixes#9095.

Additionally, in order to make the above backtrace useful,
please also run the following command to generate a disassembly of your
binary:
objdump -d `which htop` > ~/htop.objdump
and then attach the file ~/htop.objdump to your bug report.
Thank you for helping to improve htop!

Not sure whether this was broken in the first place (8cd6d53) or if it
went broken afterwards (due to the version bump in 04e39bd), but it
isn't included in the store path at current master.
So I've tested the commit and kbd now correctly includes the Neo layout.
