target.hardware: do not emit `src` attributes.

These interfere with bitstream caching.

CI: fix cache key calculation.

It turns out GitHub will not update the cache if the key already exists. Oops.

CI: remove all `if:` clauses.

These appear to basically not work properly if merge queue is enabled.

CI: fix job skip conditions.

Hopefully.

CI: only test software on push/pull_request if modified.

This should speed up the tests a bit, and we still get the full suite run
in the merge queue.

software: drop support for Python 3.8.

Even Debian oldstable has Python 3.9 now.

software: remove Python 3.7 compatibility shims.

We dropped support for Python 3.7 some time ago, so these shims were
completely unused.

support.plugin: fix the abominable workaround for Python 3.10+.
