[PATCH 3/4] generic/{102,172,347}: Adapt test for XFS on systems with 128+CPUs + SSDs

XFS will now scale by default its log size according the amount of CPUs. This
can significantly increase the log area and using hardcoded size of file size
will make the test file. Using the the X percent of the free space to create
the file will let the test proceed.

For generic/102 we also have to change the 102.out as we cannot know the
amount written data and it has to be filterred out.

For generic/172 we just use the new function to calculate file big enough
to consume most of the available space.

The generic/347 will use -l concurency=0 in case it is being run on the
XFS filesystem and mkfs.xfs already supports this option.
