bug#71796: [PATCH] Do not depend on tmpnam in posix.test.

bug#71796: [PATCH] Do not depend on tmpnam in posix.test.

[Tomas Volf]

`tmpnam' is a deprecated procedure that can be excluded during a
configure (`--disable-tmpnam').  There currently was a single test
relying on it, and therefore failing is such configuration.  This commit
switches to mkstemp instead.

* test-suite/tests/posix.test ("system*"): Use mkstemp instead of
tmpnam.
