[NO TESTS NEEDED] Create /etc/mtab with the correct ownership

Browse Source 
Create the /etc and /etc/mtab directories with the
correct ownership based on what the UID and GID is
for the container. This was causing issue when starting
the infra container with userns as the /etc directory
wasn't being created with the correct ownership.
