5c41fa2918 guix: disable libsanitizer in Linux GCC build (fanquake)

Pull request description:

  This causes issues when building against newer glibcs (i.e 2.42), and isn't needed in any case.

  ```bash
  ../../../../gcc-14.3.0/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:483:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’
    483 |   unsigned struct_termio_sz = sizeof(struct termio);
        |                               ^~~~~~~~~~~~~~~~~~~~~
  ```

  Extracted from #25573.
