profiles: 'manifest-add' truly deletes duplicate entries.

Browse Source 
Fixes <https://bugs.gnu.org/30569>.
Reported by Andreas Enge <andreas@enge.fr>.

* guix/profiles.scm (manifest-add): Don't append ENTRIES as is.
Instead, cons each element of ENTRIES as we fold over it.
Remove unneeded ellispes in 'match' patterns.
