[LTP] [PATCH] fs: exclude 'wakeup_count' from read_all_sys test.

/sys/power/wakeup_count semantics state that the read() for the file
will block as long as there is a wakeup_event in progress. On most
systems, this will be non deterministic and will result in extremely
flaky test. Exclude the file from read_all_sys test for the same.
