This is a variant of generic/477 with connectable file handles.
This test uses load and store of file handles from a temp file to test
decoding connectable file handles after cycle mount and after renames.
Decoding connectable file handles after being moved to a new parent
is expected to fail on some filesystems, but not on filesystems that
do not really get unmounted in mount cycle like tmpfs, so skip this test.
