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).
