overlay: change error to debug log for unsupported fs

The overlay driver previously raised an error when encountering an unsupported filesystem. This commit changes the error message to a debug log, allowing the overlay driver to continue its operation even with unsupported filesystems, without causing a failure. [NO NEW TESTS NEEDED] Introduced-by: containers#1374 Closes: containers#1546 Signed-off-by: Giuseppe Scrivano <[email protected]>
