build system: wrap git commands.
We need to somehow isolate the git configuration being used to build
GNU Boot from the rest of the system as otherwise things like
automatic gpg signatures can kick in and block the build because it
waits for a pinentry.

In addition:
- It enables us to simplify the build code as the git configuration is
  now the same during all the build.
- Contributors don't need to setup git anymore just to build GNU
  Boot. This also makes GNU Boot a bit more reproductible.

Replacing git inside the build scripts / Makefiles enable us to still
run them manually (like ./resources/packages/coreboot/download).

Usage:
./download <PACKAGE> <OPTIONS>
./download --help
possible values for 'package':
$(list_packages)
Example: ./download i945-thinkpads-install-utilities
Example: ./download coreboot
Some package options allow for additional parameters:
Example: ./download coreboot default
Example: ./download coreboot x60
Each package download script should work without extra paramaters, but
they can use them. For instance, './download coreboot' will download all
coreboot trees by default, but './download coreboot x60' will only
download the coreboot tree required for the target: x60
Each package download script should also accept the --help paramater to
display the usage of the script.
Refer to the documentation for more information.
