[PATCH v2] elf: Add -z lazy to some more tests

["Arsen Arsenović" <arsen@aarsen.me>]

From: Arsen Arsenović <arsen@gentoo.org>

Some toolchains, such as that used on Gentoo Hardened, set '-z now' out
of the box.  This trips up a couple of tests.

Evening,

This is a re-roll of the following patch series:
https://inbox.sourceware.org/libc-alpha/20230302112519.914641-1-arsen@gentoo.org/

Changes from v1:
- Dropped -z norelro.  This turned out to be unnecessary after
  Adhemervals removal of --with-default-link and linker script
  machinery:
  https://patchwork.sourceware.org/project/glibc/list/?series=17843
  See: https://inbox.sourceware.org/libc-alpha/86fsakz5mr.fsf@gentoo.org
  for an explanation of what caused the need for norelro.  That fix was
  misguided, due to a previous error on my part, too.
  I applied this patch on top of that patchset and it would appear to
  resolve all related failures.
  The above is not applied to Git yet, but should be before this patch
  is.
