Subject: [PATCH 02/20] Override ROOT_PATH with environmental variable

Normally ROOT_PATH is "/mnt/sysimage", but with dirinstall it would be
nice to be able to install to arbitrary directories. This lets the path
be overridden by the ANACONDA_ROOT_PATH environmental variable.

Resolves: rhbz#1113535
Port of rpmostreepayload patches from master
