Subject: [PATCH v2 3/8] generic/008: Add test for fallocate zero range at block boundary

Add test for fallocate zero range at block boundary. This is similar to
the test xfs/290 however this one is generic and we're testing different
block sizes as well - namely 1k, 2k, 4k and 64k. Note that we're not
creating file systems with given block size buy rather test all 4
options.
