[PATCH v2 2/3] t0050: honor CASE_INSENSITIVE_FS in add (with different case)

The test case "add (with different case)" indicates a
known breakage when run on a case insensitive file system.

The test is invalid for case sensitive file system, it will always fail.

Check the precondition CASE_INSENSITIVE_FS before running it.
