pcr: add guile-git for developping with guile 3GNUtoo/bootstrap/guix/guile-3

guile-git has Guile version 3.

Upstream Guix uses guile 3, while the Parabola package uses version 2.2:
    $ pacman -Q -i guix
      [...]
      Depends On      : guile>=2.2.4 [...]

This can create issues when manually compiling Guix git against Parabola
guile package and using ./pre-inst-env for testing patches before sending
them upstream: as the guile version is different, loading the compiled scm
takes a huge amount of time and we also gets warnings like that for many
files:
    ;;; WARNING: loading compiled file [...]/gnu/packages/messaging.go
        failed:
    ;;; In procedure load-thunk-from-memory: ELF file does not have native
        word size

AUR also has many packages that depend on guile which is also provided by
guile-git, however people using AUR are typically compiling the PKGBUILD
themselves, and as I understand using guile-git with packaged software
would require to recompile them for guile 3.

However in practice that breaks guix's configure as it detects that
/usr/bin/guile is not the same than the lastest guile.
