xalloc-die-tests: avoid printing null pointer

The test leaked "(null): memory exhausted" to stderr, or crashed
for less capable printf.

* modules/xalloc-die-tests (Files, Makefile.am): Wrap execution in
shell script.
* tests/test-xalloc-die.c (program_name): Declare.
* tests/test-xalloc-die.sh (tmpfiles): New file.
