Resolve dependencies whenever --syncdeps is passed and --nodeps is not

With this patch, dependencies will be resolved and not silently ignored
when running:

makepkg --nobuild --syncdeps
makepkg --repackage --syncdeps

Also, a warning is displayed when repackaging and dependencies are not
being resolved.

Thank you Allan for the feedback.
