t5601-clone: test case-conflicting files on case-insensitive filesystem
A recently introduced regression caused a segfault at clone time on
case-insensitive filesystems when filenames differing only in case are
present. This bug has already been fixed (repository: pre-initialize
hash algo pointer, 2018-01-18), but it's not the first time similar
problems have arisen. Therefore, introduce a test to catch this case and
protect against future regressions.
