mk: fix warnings when adding extra warning flags

Starting with commit 9aa2053c6e
EXTRA_CFLAGS is sometimes being passed to the compiler without
WERROR_FLAGS which can cause spurious warnings by the dozen,
for example with when compiling with EXTRA_CFLAGS="-Wformat-security":

cc1: warning: -Wformat-security ignored without -Wformat [-Wformat-security]

Passing WERROR_FLAGS to AUTO_CPU helper makes the warning flag usage
consistent throughout the codebase, silencing the warnings.

Fixes: 9aa2053c6e ("mk: influence CPU flags with user input")
