This patch changes three things:
1. package derivations are built using Guile 3.0;
2. 'gexp->derivation' defaults to Guile 3.0;
3. "guile3.0-" packages are deprecated aliases for the regular
package, which now depends on Guile 3.0; "guile2.2-" packages are
introduced; "guile-next" is renamed to "guile".
