[Libosinfo] [PATCH] build-sys: Generate glib enum files in $(builddir)

[Christophe Fergeau]

Since b4c5a1b5c which introduced the generation of an osinfo_version.h
file when configure is run, the glib enum files will be regenerated
during make distcheck instead of using the one from the tarball.
osinfo/Makefile.am currently attempts to generate these files in
$(srcdir), which causes make distcheck to fail as it makes $(srcdir)
read-only.

This patch makes sure these files are generated in $(builddir) and that
they are cleaned up afterwards.
