guix package: Add '--allow-collisions'.
Fixes <https://bugs.gnu.org/30830>. Suggested by Ricardo Wurmus <rekado@elephly.net>. * guix/scripts/package.scm (build-and-use-profile): Add #:allow-collisions? and pass it to 'profile-derivation'. (show-help, %options): Add '--allow-collisions'. (manifest-action, process-actions): Pass #:allow-collisions? to 'build-and-use-profile'. * tests/guix-package.sh: Add collision test. * doc/guix.texi (Invoking guix package): Document '--allow-collisions'.
