[PATCH -v2 1/2] ext4/045: use the large_dir feature to fix test failures with a 1k block size

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

If the file system has a 1k blocksize, this test will fail without the
large_dir file system, because the depth of the dir_index tree needs
to be greater than 2.  So enable the large_dir unconditionally, which
also gives us better test coverage of the large_dir code paths.

As a result of requiring large_dir, this test will get skipped if the
kernel is older than 4.13 --- which was released in 2017; and that
seems to be reasonable at this point.
