[Libguestfs] [PATCH] v2v: fix build rules for output_rhv_upload_*_source.ml files

[Pino Toscano]

Use the $(srcdir) variable where needed, to make sure it builds also
with srcdir != builddir.

Furthermore, make sure that the OCaml dependencies calculation depend on
the generated output_rhv_upload_*_source.ml files, otherwise there will
be incomplete OCaml rules for them in the generated .depend.

Fixes commit cc04573927cca97de60d544d37467e67c25867a7.
