Subject: units: conditionalize configfs and debugfs with CAP_SYS_RAWIO

We really don't want these in containers as they provide a too lowlevel
look on the system.

Conditionalize them with CAP_SYS_RAWIO since that's required to access
/proc/kcore, /dev/kmem and similar, which feel similar in style. Also,
npsawn containers lack that capability.

(cherry picked from commit fa229d09281d435153b4cfd138a2a62fa66d889b)
