[LTP] [COMMITTED] [PATCH] syscalls/futex: Get rid of futex_common.h

[Cyril Hrubis]

There is no point in passing fd to anynomous mapping, the fd was ignored
to begin with.

This commit just moves the mmap() to particular tests as there is no
point in having helper just for one mmap() call and removes the
futex_common.h completely.
