[LTP] Running LTP on new filesystems

This is exactly what I would have done. Most of the testcases uses
TMPDIR as a base for any temporary files and so all fs related syscalls
will end up in the right filesystem code.

There are a few testscases that use a device for testing and make
filesystem there. You have to export *FS_DEV_TYPE env variables (see
runltp -h), otherwise these default to ext2.

Sorry, we are a bit underdocumented in that area.
