[libc] Move implementations of strcat and strcpy to the string directory.

Summary:
Now that tests live in separate top-level directory, keeping the
implementations of individual functions in a directory of their own is
not meaningful. Hence, this change moves them into the higher level
string directory.

NFC intended.
