Client: Debian package fix: Make uninstall when using dracut(8) work

Use the same logic to rebuild the initramfs image when uninstalling as
when installing the package.

* debian/mandos-client.postrm (update_initramfs): Use the same logic
  as the update_initramfs function in debian/mandos-client.postinst.
