configure: test all warnings

Some warnings are hardcoded in QEMU_CFLAGS and not tested.  There is
no particular reason to single out these five, as many more -W flags are
present on all the supported compilers.  For homogeneity when moving
the detection to meson, make them use the same warn_flags infrastructure.
