lxc: Distinguish pthread_mutex_unlock error messages

The same message exists in lxclock.c and cgmanager.c, so print the
filename along with the message.

Before this patch:
lxc-destroy -n u1
pthread_mutex_unlock returned:1 Operation not permitted

After this patch:
xc-destroy -n u1
lxclock.c: pthread_mutex_unlock returned:1 Operation not permitted
