Subject: [PATCH] call dracut function for default shell

Kdump dracut hooks need to enter emergency shell, currently it directly call
"sh -i -l", with recent dracut this does not work anymore without proper ctty.

change to call dracut lib function _emergency_shell instead of directly call
'sh -i -l'

This patch depends on dracut patch:
