Infer komodo root also on azure

[larsevj]

Issue Resolves #67 Also aims to always give warning when sourcing a komodoenv made on a different rhel version. Currently the warning is only shown is the komodoenv is outdated.

Approach Check for the existence of "/prog/komodo" and prefer this over "/prog/res/komodo".
