GNU Coreutils now built in basic dependencies

GNU Coreutils are basic programs that can help in the configuration of
higher-level programs. Because of that, it was a dependency of almost all
software built in `dependencies.mk'. To make things more clear, easier to
read and faster (when building in parallel), the building of Coreutils is
now moved to the `dependencies-basic.mk' rules. There, it is built
along-side Bash. Since `dependenceis-basic.mk' is run and completed before
`dependencies.mk', with this, we can be sure that Coreutils is present by
the time we want to build the higher-level programs.

Also, Zlib is now added as a dependency of Git also (it is necessary for
its build).
