vyos.util: T2720: Add file descriptor support to chmod and chown

Extended the chmod() and chown() functions in vyos.util to also operate
on open file descriptors in addition to paths. This allows code that
creates files to quickly change mode and owner even before anything
has actually been written to the file.
