Add Guile 3.0 as a possible GUILE_PKG

[a-sassmannshausen]

Currently building of guile-dsv using Guile 3.0 or higher fails because configure only checks for Guile 2.0 or 2.2. Adding 3.0 as an option should fix this.

Feel free to merge the pull request or follow your own workflow. I think this should fix the issue, but you may want to test first (I have not had a chance to do so!).

I encountered the issue whilst bumping the guile-dsv guix recipe and trying to add a guile3.0 recipe on top of the current 2.2 recipe.

I decided to do the same thing before I saw this thread. I have tested it a little bit. guile-dsv builds and its tests pass, and some rudimentary use at the REPL works.

In addition to adding 3.0 to GUILE_PKG, I updated guix.scm and re-orered GUILE_PKG to prefer newer Guile. These changes are on my guile-3.0 branch to use as you would like.

So ideally @artyom-poptsov might be able to merge in your commits when they have a moment. Happy to drop this pull request when that happens.

I will then add a guile 3.0 package variant to Guix.
