[4/8] misc: avoid tests encoding FIEMAP/BMAP golden output with weird file blocksizes

From: Darrick J. Wong <[e-mail]>

Some tests encode FIEMAP/XFS_IOC_BMAP results in the golden output.
Typically these tests cannot handle a filesystem that chooses to
allocate extents that are much larger than the filesystem block size
(aka XFS rt extents and ext4 bigalloc).  Since these tests are /never/
going to pass, disable them when these configurations are detected.
