[m-dev.] diff: delete unused autoconf test for tempnam()

[Fergus Henderson]

Estimated hours taken: 0.25

configure.in:
runtime/mercury_conf.h.in:
	Delete the test for tempnam(), since we don't use it.
	(It's not part of the ANSI or POSIX standards, and
	the Linux man page says "Never use this function.",
	so we're unlikely to want it in the future either.)
