[PATCH] futex: Remove <linux/futex.h> inclusion which is not used

[Eugene Syromyatnikov]

configure script doesn't perform check for linux/futex.h presence, so
HAVE_LINUX_FUTEX_H is always undefined and inclusion of system header is
never performed. Moreover, this header had an incorrect definition of
FUTEX_WAIT_BITSET_PRIVATE/FUTEX_WAKE_BITSET_PRIVATE in the past: from
commit v2.6.24-6320-gcd68998 (where these definitions had been initially
introduced) up to v2.6.31-7082-gf8d1e54 (where they have be finally
fixed) these macros has been incorrectly defined via
FUTEX_WAIT_BITS/FUTEX_WAKE_BITS (not FUTEX_WAIT_BITSET/FUTEX_WAKE_BITSET)
and these incorrect definitions made their way in some distributions still
in use.

* futex.c: Remove conditional <linux/futex.h> inclusion: HAVE_LINUX_FUTEX_H
  is never defined and this is dead code, effectively.
