[klibc] trap: Globally rename pendingsigs to pending_sig

This variable does not contain "sigs" (plural).
It contains either 0 or (one) signal number of a pending signal.

For someone unfamiliar with this code, "pendingsigs" name is confusing
-
it hints at being an array or bit mask of pending singnals.
