kola: Shorten TPM test name to keep the socket path under the limit

[pothos]

The TPM directory is created under the _kola_temp folder for the VM. In total the path used for the swtpm socket was above the 108 char limit for some tests.
Shorten the affected test names to keep the socket path under the limit.

How to use

Rerun Jenkins tests with this

Testing done

Tests passed for qemu on amd64 and qemu_uefi on arm64

For Beta arm64 I saw even the basic clevis root/nonroot test failing but there is no socket-related error message:
http://jenkins.infra.kinvolk.io:8080/job/container/job/test/21731/consoleFull I don't know yet what else might have changed. Originally the socket was under a tempdir in /tmp. Since this new longer path works on amd64 it might be something else, e.g., a forgotten backport from main to the last Alpha branch.

Found it, the arm64 kernel module change was missing: flatcar/scripts#1755

I think we could even drop the cl ... but it should be enough now. Thanks!

@pothos @tormath1 the swtpm process can be changed to run with working directory set to the tpm folder :)

Right, or even the folder above the tpm folder would be equally good, initially I considered reverting to /tmp mktmpdir stuff but your idea is better :D It's strange that this kernel limitation is for relative paths and not for the full path.

Turned out to be a bit more complicated because qemu also needs to run with that working dir to have a short socket path argument: #526
