vfio: selftests: Add -Wall and -Werror to the Makefile

Add the compiler flags, -Wall and -Werror, to catch all the build
warnings and flag them as a build error, respectively. This is to
ensure that no obvious programmer errors are introduced. We can
add -Wno-* flags in the future to ignore specific warnings as necesasry.
