ZTS: Fix nonportable use of stat in list_file_blocks

FreeBSD stat uses -f to specify the format string rather than -c.
list_file_blocks in blkdev.shlib uses stat -c %i to get a file's
object ID for zdb.  We already have a library function to do this
portably.

Use get_objnum to get the file's object ID.

Take log_must off of the call to list_free_blocks in
corrupt_blocks_at_level, which had masked the error.  It was not good
to pipe the output of log_must into the while-loop, anyway.
