Updated armband

Project: fuel  de6d5d4b6ba6848304d620e65ad97f3aeeadccd5

docs: build req: Remove p7zip-full

p7zip-full is not required for building, as stated in the current
version of the docs. I think this bogus requirement was introduced
by Armband (by me, more precisely) because our build process was
happening outside docker.

Sorry for the useless code churn.
