[PATCH 1/3] xfstests: move generic indlen reservation test to xfs dir

[Brian Foster <bfoster@redhat.com>]

This test was originally designed to reproduce the split indlen
reservation depletion problem in XFS. It was included as a generic test
simply because it had no hard dependencies on XFS or associated tools.

This test is no longer effective in its current form. Fixing it requires
use of XFS specific mechanisms. Therefore, move the test to the XFS
specific test directory. No other changes are made in this patch.
