qemu: Update glib to build on newer gcc

Update the glib version to 2.48.2 in order to fix build failure on newer
gcc[0].

Force internal version of libpcre for glib, since otherwise the build
failed, presumably since libpcre is not provided as a module (maybe it
should?).

Increasing the glib version further to the current latest was not
tested.
