Add missing syscall wrapper on Solaris

Browse Source 
I tried to test drd/tests/pth_mutex_signal on Solaris
(you never know) but encountered a missing syscall
wrapper. So this adds a very basic wrapper for lwp_mutex_unlock.

Also update a Solaris expected that I missed amongst the FreeBSD changes.
