Use .zephyrrc for initializing common variables 

The file can be used to define variables used by the SDK to avoid
having to define them everytime a session is started.

The old file names ~/zephyr-env_install.bash will still work but
it will warn about the file being renamed. We do not want to break
users who have ~/zephyr-env_install.bash in their home and depend on
it.
