systemctl suspend-then-hibernate attempts hybrid-sleep instead

[Robert Collins]

[impact]

suspend-then-hibernate not possible using systemctl

[test case]

configure a system (that has enough swap to be able to hibernate) to allow suspend-then-hibernate but not hybrid-sleep, e.g. by editing /etc/systemd/sleep.conf to set AllowSuspendThenHibernate=yes and AllowHybridSleep=no, then try it:

$ sudo systemctl suspend-then-hibernate
Failed to suspend system, hibernate later via logind: Sleep verb "hybrid-sleep" not supported

note that on bionic, the Allow...= params do not exist, instead we can reproduce the error by setting one of the hybrid parameters to an invalid value, e.g. HybridSleepState=bugverification

[regression potential]

failure to correctly enter hybrid-sleep and/or suspend-then-hibernate, or other issues around suspending/hibernating

[scope]

This is needed in b and later.

The bug appears to have been introduced by a typo in the original suspend-then-hibernate commit c58493c00af, and then fixed with larger changes in commit c8cd8ca3986.

this is also present in b, by a backport of the functionality

[other info]

note that if hybrid-sleep is allowed/possible, then calling 'systemctl suspend-then-hibernate' does actually perform suspend-then-hibernate; this typo only controls what suspend action logind checks for support of, not what suspend action it actually performs.

[original description]

```
systemctl suspend-then-hibernate
Failed to suspend system, hibernate later via logind: Sleep verb "hybrid-sleep" not supported
```

Note the verb change!

This bug was fixed in the package systemd - 248.3-1ubuntu7

---------------
systemd (248.3-1ubuntu7) impish; urgency=medium

  * d/tests/tests-in-lxd: suppress the cgroups v2 warning on stderr from
    lxd/lxc even more comprehensively until the snapd change required to
    do it nicely gets into a release.
