guix: remove -Werror=dev

Otherwise the build will fail with warnings about missing Python (removed
in the next commit). However the non-gui build does not need Python.

Note that #25573 contains the same change, because the use of -static-pie
causes warnings when combined with our/CMakes own PIE handling.
