libprocessgroup: Add fd caching support for SetProcessProfiles

Process profiles operating on paths that do not depend on pid or uid of
the process can cache the fd of the file they are operating on. Add
support for fd caching similar to how SetTaskProfiles caches the fd
of the file it needs to write to.
