[bug#40423] [PATCH] system: Split %BASE-PACKAGES in smaller parts.

[Brice Waegeneire]

* gnu/system.scm: (%base-packages-interactive, %base-packages-linux,
%base-packages-networking, %base-packages-utils): New variables.
(%base-packages): Use those new variables.
---

This patch split %base-packages to make it more reusable. We talked about it
with John Soo on IRC[0] and on the ML[1].
