setup_{RedHat,Debian}.sh, make more idempotent

Browse Source 
Previously, when either setup_{RedHat,Debian}.sh was ran
multiple times a mess was created due to multiple loop
devices being setup.

This change now looks to see if '/docker' or '/swapfile'
already exist, and not re-create them if they do.

*However*, /var/lib/docker (/docker) is still wiped - but it
means that the script can run and bring the system into a
constant vanilla state.
