While setting up a build environment for Borg from Guix commit
9e783d0bf22a7ff965105eb45f6c179a832bbabf, I noticed a profile collision
between python-six and python-six-bootstrap, with the bootstrap package
winning the contest:

These package "bootstrap" packages shouldn't be referenced in profiles,
right?
