osmo_escape_str_buf: Always copy, don't return input string pointer

osmo_escape_str_buf() used to have the somewhat odd semantics that
if no escaping was needed, it would return the original pointer without
making any copy to the output buffer.  While this seems like an elegant
optimization, it is a very strange behavior and it works differently
than all of our other *_buf() functions.  Let's unify the API and
turn osmo_escape_str_buf() into a strlcpy() if no escaping is needed.
