[PATCH 4/5] ext4/054: skip test if the dax mount option is enabled

["Theodore Ts'o" <tytso@mit.edu>]

The ext4/054 test explicitly creates a file system with a 1k
blocksize.  This can't possibly work on if the dax mount option is
enabled, so change ext4/054 to use _scratch_mkfs_blocksized, and and a
check to _scratch_mkfs_blocksized to _notrun the test if the block
size is less than the page size.

Also remove an unnecessary _require_test declaration since this test
does not use the test device.
