libmbim doesn't distcheck

[Dan Williams]

Hey,

Was trying to distcheck libmbim today so I could propose it for Fedora,
and it fails because the tests try to look for the codegen-ed files in
$(top_builddir)/libmbim-glib/generated/, but they aren't there, they are
actually generated in $(top_srcdir)/libmbim-glib/generated/.  Are the
generated files expected to be DIST-ed, or is the tarball expected to
re-generate them?  The core error is:

gcc -DHAVE_CONFIG_H -I. -I../../../libmbim-glib/test -I../..  -pthread
-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include

This fails because ../../libmbim-glib/generated (which is actually
libmbim-1.5.0/_build/libmbim-glib/generated) only contains the compiled
generated files, but doesn't contain the generated files themselves.
Those are still in $(top_srcdir)/libmbim-glib/generated/.
