profiles: 'check-for-collisions' filters out more non-collisions upfront.

When running:

  GUIX_PROFILING="gc object-cache" ./pre-inst-env \
    guix install gnome -p /tmp/sdsdfsd --no-grafts -n

this reduces the number of object cache lookup from 115K to 96K, with a
slight CPU and memory usage reduction as well.

* guix/profiles.scm (check-for-collisions)[candidates]: Exclude entries
if their 'item' fields are eq?.
