[PATCH v2 0/9] TLV integration tests and test/py cleanup

[Jonas Rebmann]

With TLV signature coming up, we want to test all things TLV more
thoroughly, including "roundtrip" integration tests that include the
bareboxtlv-generator python-script and the tlv barebox-command.

As this is the third test module to make use of the testfs, it seemed
adequate to revisit its implementation.

Avoid integration test logic outside pytest; migrate logic from .github/
and scripts/ into pytest.

Use fixtures for testcase preconditions and migrate existing testdata
preparation from scripts/generate_testfs.sh.

Cleanups here and there.

The ci-container needs to be rebuilt before the TLV tests will succeed
in CI.

Changes in v2:
- work around a corner case where a failed network test leads to
  unrelated pritinting above the tlv command output (triggered by
  accessing the 9pfs)
- move fitimage testdata generation to fixture and drop script
- Enable CMD_TLV for multi_v7 and multi_v8 (required for tlv_command test)
- Skip tlv_command test if CMD_TLV is disabled
- Ensure that pwd is returned to / after dm_verity test even on failure
- Silently skip generating testdata for the fit tests for platforms for
  which no files are provided to prevent ci failure on mips and riscv
- minor improvements in style and consistency
- Link to v1: https://lore.barebox.org/barebox/20250926-tlv-integration-v1-0-45dc68b9b602@pengutronix.de
