tests: Fix OOM eloop_register_sock() test cases with new gcc

gcc 4.8 vs 5.2 seem to compile eloop_register_sock() differently. With
5.2, that function name does not show up in the backtrace since
eloop_sock_table_add_sock() is used without a separate function call.
This broke the memory allocation failure checking in this test case. Fix
this by matching against the eloop_sock_table_add_sock() function which
shows up in the backtrace for both gcc versions.
