meson tests sharing a binary (and deviating in their env/args) will produce temporary logs to the same directory, which is assumed to exist only for the duration of a single test. This is problematic when running tests in parallel, as one test may remove the directory before the other(s) finish, causing a test flake. This appends the each test's pid to the output directory to enforce uniqueness and avoid the race.
