Fixup gdb-rhbz1156192-recursive-dlopen-test.patch

- Fix __malloc_check usage to fix "free: invalid pointer" error with
  GLIBC_TUNABLES=glibc.malloc.check=3.
- Handle older libc, for which we run into glibc PR17702:
  Inconsistency detected by ld.so: dl-open.c: 222: dl_open_worker: Assertion \
  `_dl_debug_initialize (0, args->nsid)->r_state == RT_CONSISTENT' failed!
