Allow use of robust list syscalls

Browse source 
The set_robust_list syscall sets the list of futexes which are
cleaned up on thread exit, and are needed to avoid mutexes
being held forever on thread exit.

See for example in Musl libc mutex handling:
http://git.musl-libc.org/cgit/musl/tree/src/thread/pthread_mutex_trylock.c#n22
