bpf: selftests: global_funcs: Check err_str before strstr
[ Upstream commit c210773d6c6f595f5922d56b7391fe343bc7310e ]
The error path in libbpf.c:load_program() has calls to pr_warn()
which ends up for global_funcs tests to
test_global_funcs.c:libbpf_debug_print().
For the tests with no struct test_def::err_str initialized with a
string, it causes call of strstr() with NULL as the second argument
and it segfaults.
Fix it by calling strstr() only for non-NULL err_str.
