Merge bitcoin#25437: guix: remove explicit glibc stack protector disabling

4e569c8 guix: remove explicit glibc stack protector disabling (fanquake)

Pull request description:

  While glibc 2.25 and newer *can* be built with stack-smashing-protection
  enabled, it isn't used by default, and still isn't, as of glibc 2.35,
  so I can't see a reason to explicitly disable it.

  I'd also like to move in the direction of enabling, by default,
  hardening options for the toolchains we build, so removing the explicit
  disabling is a step in that direction.

  Will be following up with some changes based on this change.
