import: crate: Use guile-semver to resolve module versions.

Browse source 
* guix/import/crate.scm: Add guile-semver as a soft dependency.
  (make-crate-sexp): Don't allow other keys. Add '#:skip-build?' to build
  system args. Pass a VERSION argument to 'cargo-inputs'.
  (crate->guix-package): Use guile-semver to resolve the correct module
  versions. Treat "build" dependencies as normal dependencies.
  (crate-name->package-name): Reuse the procedure 'guix-name' instead of
  duplicating its logic.
* guix/import/utils.scm (package-names->package-inputs): Implement
  handling of (name version) pairs.
* guix/scripts/import/crate.scm (guix-import-crate): Use
  crate-recursive-import instead of duplicate code.
* tests/crate.scm (recursive-import): Change test packages versions to be
  distinguishable. Add version data to the test. Check created symbols, too.
