kdumpctl: skip selinux-relabel for dracut_args --mount dump target

Browse Source 
When using "dracut_args --mount" to specify dump target, e.g. nfs like:
    path /
    core_collector makedumpfile -d 31
    dracut_args --mount "host:/path /var/crash nfs defaults"
kdump service should neither guarantees the correctness, nor relabels it.

For current code, since dracut_args dump targets are likely not mounted
so kdump service mistakenly relabel the rootfs, which is meanless and
takes very long time.
