initscripts: add /sbin/sushell for systemd service debug-shell
Add file /sbin/sushell for systemd service debug-shell which starts with
/bin/sushell when SELinux is enabled. Copy and add sushell file from
Fedora 22.
Add runtime dependency bash as well when systemd is enabled to eliminate
QA warning:
