Daniel P. Berrangé c5f1d0c493 util: remove redundant include of glib.h and add osdep.h
Code must only ever include glib.h indirectly via the glib-compat.h
header file, because we will need some macros set before glib.h is
pulled in. Adding extra includes of glib.h will (soon) cause compile
failures such as:

In file included from /home/berrange/src/virt/qemu/include/qemu/osdep.h:107,

/usr/include/glib-2.0/glib/gversionmacros.h:237: note: this is the location of the previous definition
 # define GLIB_VERSION_MIN_REQUIRED      (GLIB_VERSION_CUR_STABLE)

Furthermore, the osdep.h include should always be done directly from the
.c file rather than indirectly via any .h file.
