Subject: [PATCH] ftests: Add support for running 'sudo' suite of tests

Some tests require sudo support for python/C bindings.  This is
awkward to implement using the Run() class and error prone.

Instead, invoke the entire test with sudo permissions via a separate
invocation of ftests.py.  This ensures that existing tests (that
don't require sudo) remain the same and don't accidentally get
elevated privileges.
