runner_tests: Fix the file descriptor leakage subtest

Some libraries (looking at you, GnuTLS) may leave fds opened after the
implicitly called library constructor. We don't have full control over
them as they may be dependencies of our dependencies and may get pulled
in if the user's and distribution's compile/configure/USE are just
right.

Let's close all the non-standard fds ahead of executing anything in the
igt_runner tests, so we can test for descriptor leakage caused by any of
the igt_runner code-paths exercised there.
