target/hexagon: add flex/bison/glib2 to qemu.yml

Note, the glib2-native mapping exists separately from the normal glib2
mapping. The latter uses a `foreign` cross-policy-default, and
libvirt-ci is not able to support package mappings for multiple
cross-compilation policies.

This will probably change in the future.
