[ovs-dev] [PATCH 1/3] tests: Make test for Linux /proc/self/fd more straightforward.

[Ben Pfaff]

Presumably we can test for this Linux feature just by seeing whether the
directory is there.

Another goal is to shorten the code because I intend to make another copy
of it in an upcoming commit, to add a similar test for Python.
