commonlib/bsd: Optimize strnlen()
This patch changes the strnlen() implementation to fix a small issue where we would dereference once more byte than intended when not finding a NUL-byte within the specified amount of characters. It also changes the implementation to rely on a pre-calculated end pointer rather than a running counter, since this seems to lead to slightly better assembly (one less instruction in the inner loop) on most architectures.
