kernel: disable CONFIG_WERROR

Browse Source 
The help of this options says:

"However, if you have a new compiler with ..., you may need to disable
this config option in order to successfully build the kernel."

As we are having state-of-art GCC-12, and Linux-5.18 release candidate
FTBFS with GCC-12 and CONFIG_WERROR=y [1], and <rant>the kernel developers
are making stupid and meaningless discussion instead of fixing the building
failure</rant> [2], I don't think enabling this option makes any sense
building LFS.
