[LTP] [PATCH] futex: skip futex_wake04.c if system not support huge pages

[Li Wang]

Testcase fails on system which not support hugepages:

futex_wake04    1  TBROK  :  safe_file_ops.c:155: The FILE '/proc/sys/vm/nr_hugepages' ended prematurely at futex_wake04.c:74
futex_wake04    2  TBROK  :  safe_file_ops.c:155: Remaining cases broken

Skip the testcase cases with TCONF rather than failing with TBROK.
