Mirror vfd test fixes (#1629)

* Use the FAPL that was created earlier in the test (and delete an unused
variable).   This allows 'make check-vfd' to pass with --enable-mirror-vfd.

* Check for testing directory before creating, to avoid warning from bash.
Clean out .libs directory before re-using it (after a failed test), to
remove any files generated by libtool.

* Committing clang-format changes

* Increment error count on failed file open and skip tests for VFDs that need
modified filenames.

* Skip the mirror VFD for 'make check-vfd' - the mirror VFD requires networking
configuration parameters and can't be provided for an automated test that
is configured with an environment variable.
