osdep.h: Include glib-compat.h in osdep.h rather than qemu-common.h

Our use of glib is now pervasive across QEMU. Move the include of glib-compat.h
from qemu-common.h to osdep.h so that it is more widely accessible and doesn't
get forgotten by accident. (Failure to include it will result in build failure
on old versions of glib which is likely to be unnoticed by most developers.)
