Get dir locations from environment

Get dir locations from environment

[Problem] Key manager data dir location was hardcoded to /opt/data/ckm/. On
common profile image key-manager fails to start because of lack of /opt/data.
[Solution] Get directory locations from tizen platform config. Copy files
from old location if necessary. Make installation fail if runtime and compile
time settings differ. Provide upgrade script.

[Verification] Install key-manager package. Make sure all the content from
/opt/data/ckm/ has been moved to new location (/usr/data/ckm). Run tests. Make
sure all data is placed in new location. Run upgrade scripts
(/etc/opt/upgrad/*key-manager*.sh) on old version of ckm and check results.
