[LTP] [PATCH STAGING v2 04/16] fchroot01: test fchroot() with a directory fd

I do not think that we need this. The process that runs the run()
function is forked from the library process in order for the test to be
isolated from the library.

As long as we do not have a custom cleanup() function that needs to run
outside of the jail we do not have to fork in the run().
