ruby: Make reproducible
Bundled gems that have native extensions have a gem_make.out file that
is the build log for the native extension. That file contains random
filenames. Since this file is not needed, simply remove it.
With this change, ruby_3_1 build is reproducible, at least on
x86_64-linux.
Example `diff -ur` from `nix build --rebuild --keep-failed .#ruby_3_1`,
before this change:
