Revert "libc: remove unused strings for Scorpion and use Denver memmove"

This Vanir's bionic.
Vanir's anzu, coconut, and codina didn't build with this commit. 
I'll take a shot in the dark, and blame it.
Test commits on Vanir, or don't merge them to Vanir... ESPECIALLY SHIT LIKE BIONIC.

This reverts commit c4c6723315246b28bfce38eee93ccb59fd59354c.
