signal: sigprocmask: narrow the scope of ->siglock
No functional changes, preparation to simplify the review of the next change.
1. We can read current->block lockless, nobody else can ever change this mask.
2. Calculate the resulting sigset_t outside of ->siglock into the temporary
variable, then take ->siglock and change ->blocked.
Also, kill the stale comment about BKL.
