Removed libclone from Makefile and used LTP API to replace it.
mountns01 has been adapted to use the new LTP API.

Again there is no need to propagate results via exit value like this,
the tst_res() function will work in the child just fine.

And the segfault will be caught by the test library, so no need to wait
for the child here as well.
