initscripts: split sushell into sub package
* sushell is required by systemd service debug-shell
when selinux is enabled, but it doesn't make sense
to make systemd depend on initscripts, so split sushell
into sub package initscripts-sushell.
* The bash dependency has been removed by:
'''

initscripts: Fix regression for requiring /bin/bash
'''
so remove bash from RDEPENDS when selinux is enabled.
