That was maybe how we intended it but we exposed the API and it seems
that there is a usecase for it so people are possibly using it.

There is a usecase we haven't figured out, when you want to test a
single filesystem, you do not want to waste time on the rest of the
filesystems and LTP_SINGlE_FS_TYPE nearly works for that usecase.
