python3-filelock: fix ptest cache-dir permissions and missing tasks/pythonpath

tests/ imports itself as "tests.*" and pulls in "capabilities" from
the sibling tasks/ dir; upstream's pyproject.toml sets
[tool.pytest] pythonpath = [".", "tasks"] to make both resolve, so
ship tasks/ and pyproject.toml into the ptest install too.

Also disable pytest's cache plugin: the non-root "tester" user ptest
runs as can't write a cache dir under the read-only-to-them
/usr/lib/python3-filelock/ptest install path.

Add python3-pytest-timeout, used by the test suite.
