[LTP] [PATCH] futex_waitv04: Add test for futex_waitv syscall

[zhaogongyi]

Hi Cyril,

I also wondered whether to add these two testcases into futex_waitv01.c, there is a consideration that there are alse two other testcases need to be added according to linux manual:

1. A signal was sent to the sleeping task, returning -ERESTARTSYS.
2. Some futex at the list was woken, returning the index of some waked futex.

Best wishes!

Gongyi
