#1437267 — [PATCH v2 4/7] staging: speakup: replace spk_strlwr() with strncpytolower()

After introducing generic strntolower() and strtolower(), spk_strlwr()
is no longer needed.

Samuel, I left off your ACK, since the implementation of my function changed
somewhat (no check for NULL, return value is different). Please let me know
if you are still okay with this.
