bug#26271: 'guix system' does not support common build option '--root'

That’s because ‘--root’ is not a “common build option” in the sense of
"(guix) Common Build Options".  :-)

That said, I agree we should either make it a common option (i.e., add
it to ‘%standard-build-options’ in (guix scripts build)) or add it
explicitly to ‘guix system’.  The latter may be simpler.

Thoughts?
