Remove the kdump error handler isolation wrapper
The wrapper is introduced in commit 002337c, according to the commit
message, the only usage of the wrapper is when dracut-initqueue calls
"systemctl start emergency" directly. In that case, emergency
is started, but not in a isolation mode, which means dracut-initqueue
is still running. On the other hand, emergency will call
"systemctl start dracut-initqueue" again when default action is dump_to_rootfs.
systemd would block on the last dracut-initqueue, waiting for the first
instance to exit, which leaves us hang.
In previous commit we added initqueue status detect in dump_to_rootfs,
so now even without the wrapper, it will not hang.
And actually, previously, with the wrapper, emergency might still hang
for like 30s. When dracut called emergency service because initqueue
timed out, dump_to_rootfs will try start initqueue again and timeout
again. Now with the wrapper removed, we can avoid these two kinds of
hangs, bacause without the isolation we can detect initqueue service
status correctly in such case.
Also remove the invalid header comments in service file, the service
is not part of systemd code. And sync the service spec with dracut.

Make dracut-squash required for kexec-tools
This patch reverts commit "Make dracut-squash a weak dep".
Although kexec-tools can work without dracut-squash, it is essential
for kdump to run properly in cases [1][2] where minimal amount of memory
consumption is expected. Thus dracut-squash is needed for it.
