[Bug 1862657] [NEW] systemd autopkgtest 'logind' fails when running with linux-kvm

[Dan Streetman]

Public bug reported:

[impact]

the logind autopkgtest tries to access /sys/power/state, but because
linux-kvm has CONFIG_PM unset, there is no /sys/power/state file

[test case]

check autopkgtest, e.g.:
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-eoan/eoan/amd64/s/systemd/20200210_144351_da247@/log.gz

autopkgtest [13:48:53]: test logind: -----------------------]
autopkgtest [13:48:53]: test logind:  - - - - - - - - - - results - - - - - - - - - -
logind               FAIL stderr: grep: /sys/power/state: No such file or directory
autopkgtest [13:48:53]: test logind:  - - - - - - - - - - stderr - - - - - - - - - -
grep: /sys/power/state: No such file or directory

[regression potential]

regressions would likely involve incorrectly skipped logind test.

[scope]

this fails for all releases; Xenial, Bionic, Eoan, and Focal.

[other info]

it's unclear if linux-kvm should have CONFIG_PM (and other config)
enabled or not.

However, it's not the intention of systemd's autopkgtests to look for
missing config in the kernel; the test already skips if 'mem' isn't in
/sys/power/state, so it should also skip if /sys/power/state isn't
present at all.
