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.
