[PATCH 2/2] buildchroot: Assert that we are one of the two valid users

[Henning Schild <henning.schild@siemens.com>]

Everything we do inside the buildchroot should be done as "root:root" or
"builder:builder" and we depend on "builder:builder" being in sync with
the ids in the system we chroot from.

This assertion will find violations or the odd case where the ids got
out of sync.
