open_by_handle: add -s option to sleep and keep files open by handle
This feature is needed for tests that need to open file by handle and
then perform operations while that file is open. This will be used by
an overlay test to keep disconnected dentries in dcache.
Usage: open_by_handle -s <test_dir>
On success, the program will run until it gets a terminating signal.
