Merge swtpm from Debian unstable

[Jeremy Bícha]

Please merge swtpm from Debian. It looks like swtpm was independently
packaged in Debian and in Ubuntu around the same time.

Work is needed to reconcile the differences.

Changelog entries since current kinetic version 0.6.3-0ubuntu3:

swtpm (0.7.1-1) unstable; urgency=medium

  * New upstream version 0.7.1
  * Fix a security issue, CVE-2022-23645

At this point in time this would require a feature freeze exception. Do you mind writing one Jeremy?

[Jeremy Bícha (jbicha)]

I don't need this for Kinetic.

I only noticed this package because its autopkgtests regressed. But that's not currently blocking anything any more.

As the Ubuntu and Debian SWTPM packaging have no shared history, and there isn't any particular reason driving this for Kinetic, I suggest we defer a merge until LL.

The tests are weird though. They jumped from taking ~10 minutes to hitting timeout at almost 3 hours.

I suggest we leave this bug as is - the merge request is valid - and if swtpm continues to block other packages we sort out why things are taking too long.
