lvm2-lvmlocking.service incorrectly uses nonexistent option --lock-opt autowait

[WGH]

The lvm2-lvmlocking.service systemd unit installed by lvm2-lockd package has the following line:

# start lockspaces and wait for them to finish starting
ExecStart=@SBINDIR@/lvm vgchange --lock-start --lock-opt autowait

This is unfortunately wrong: the autowait option was dropped in this commit: https://www.redhat.com/archives/lvm-devel/2015-July/msg00091.html, and attempting to specify it causes the opposite effect: no waiting is done at all.

It should've said --lock-opt auto.

[WGH (wgh)]

https://www.redhat.com/archives/lvm-devel/2020-April/msg00017.html fixed upstream, but still affects both Ubuntu 18.04 and 20.04 (/lib/systemd/system/lvm2-lvmlocking.service and /lib/systemd/system/lvmlocks.service correspondingly)
