stdlib.h declares rand_r if __USE_POSIX; i.e., POSIX.1:1990. But
rand_r was added along with threads, so the condition should be
__USE_POSIX199506. This patch corrects the condition.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
[The XFAIL removal depends on
<https://sourceware.org/ml/libc-alpha/2016-05/msg00093.html> (pending
review) to eliminate the other cause of failure for the test in
question.]

[BZ #20074]
* stdlib/stdlib.h (rand_r): Declare if [__USE_POSIX199506], not if
[__USE_POSIX].
* conform/Makefile (test-xfail-XPG4/stdlib.h/conform): Remove
variable.
