tmpnam: allow slightly longer temp directory name 

ORCA/C's tmpnam() implementation is designed to use prefix 3 if it is defined and the path is sufficiently short. I think it was intended to allow up to a 15-character disk name to be specified, but it used a GS/OS result buffer size of 16, which only leaves 12 characters for the path, including initial and terminal : characters. As such, only up to a 10-character disk name could be used. This patch increases the specified buffer size to 21, allowing for a 17-character path that can encompass a 15-character disk name.
