Subject: meson: get glib compilation flags from GLIB_CFLAGS

The glib compilation flags were added to QEMU_CFLAGS.  While we still
want them to be added to all compilation commands (at least for now),
do that via GLIB_CFLAGS rather than via QEMU_CFLAGS.  This shows that
glib is a special case and makes it clearer that QEMU_CFLAGS is only
about compiler commands and not dependencies.
