environment: Disable profile collision checks.
Reported by Efraim Flashner. This is a followup to a654dc4bcf7c8e205bdefa1a1d5f23444dd22778. * guix/profiles.scm (profile-derivation): Add #:allow-collisions? and honor it. * guix/scripts/environment.scm (inputs->profile-derivation): Pass #:allow-collisions? #f to 'profile-derivation'. * tests/guix-environment.sh: Test "guix environment guix".
