[libbacktrace] Add allocfail.sh test-case

Add test-case that forces alloc.c functions to fail, and check whether fail
handling is robust.

This is the test-case for "[libbacktrace] Fix segfault upon allocation
failure".  Without that patch, this test-case fails like this:
...
allocfail.sh: line 71: 26041 Segmentation fault      (core dumped) \
  ./allocfail $i > /dev/null 2>&1
Unallowed fail found: 13
FAIL allocfail.sh (exit status: 1)
...

This is a seperate patch because the test-case is nontrivial.

Bootstrapped and reg-tested on x86_64.

2018-12-12  Tom de Vries  <tdevries@suse.de>

	* Makefile.am (TESTS): Add allocfail.sh.
	(check_PROGRAMS): Add allocfail.
	* Makefile.in: Regenerate.
	* instrumented_alloc.c: New file.  Redefine malloc and realloc.
	Include alloc.c.
	* allocfail.c: New file.
	* allocfail.sh: New file.
