Switch root is never used for kdump image, and this will be helpful to
reduce the initramfs size.
Also increase dracut dependency version and the function is
dracut_no_switch_root is new introduced.
This commit is applied to RHEL some time ago, but missing in Fedora as
Fedora's Dracut didn't backport this feature at that time. Now apply
this missing commit.
