agent_upstart_teardown.py created its fixture job directory with a bare
mkdir, so under a caller umask of 002 (the default on pulse-dev and other
Ubuntu user-private-group hosts) the directory came out 775. The
installer's trusted_lifecycle_regular_file check correctly refuses a
config whose parent is group-writable, and 23 subtests failed when the
harness ran directly. The Go driver only passed because the
installtests package pins umask 022 for its children.
Give the job directory an explicit 0755 mode, matching the sibling
TrueNAS and uninstall-state harnesses, which already create their
trust-checked directories with explicit modes. The production code
under test still runs with the caller's umask; it sets 644 on the files
it writes, so the harness now passes under 002, 022 and 077.
