[PATCH RFC next 18/18] buildman: set W flag to e to be consistent with CONFIG_WERROR

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

Buildman currently only enables Werror for KBUILD_CFLAGS (via KCFLAGS)
and KBUILD_HOSTCFLAGS (via HOSTCFLAGS) but nothing else.

scripts/Makefile.extrawarn now supports --fatal-warnings for the linker
and assembler, which are enabled whenever CONFIG_WERROR is set.

Let's make buildman set this variable to enable even more checks.
KBUILD_CFLAGS and KBUILD_HOSTCFLAGS are kept in case buildman is run on
a git-range where W=e is not available, it's better than nothing.
