incus, machinectl, run0 - fix become over pty connections (#11771)
* incus, machinectl, run0 - fix become over pty connections
Four small fixes across three plugins, all discovered while trying to
use community.general.machinectl (and later community.general.run0)
as become methods over the community.general.incus connection.
Core bug: machinectl and run0 both set require_tty = True, but the
incus connection plugin was ignoring that hint and invoking
'incus exec' without -t. Honor require_tty by passing -t, mirroring
what the OpenSSH plugin does with -tt.
Once the pty is in place, both become plugins emit terminal control
sequences (window-title OSC, ANSI reset) around the child command
that land in captured stdout alongside the module JSON and trip the
result parser with "Module invocation had junk after the JSON data".
Suppress that decoration at the source by prefixing the constructed
shell command with SYSTEMD_COLORS=0. TERM=dumb would work too but
has a wider blast radius (it also affects interactive tools inside
the become-user session); SYSTEMD_COLORS is the documented
systemd-scoped knob.
run0 was also missing pipelining = False. When run0 is used over a
connection that honors require_tty, ansible's pipelining sends the
module source on stdin to remote python3, which cannot be forwarded
cleanly through the pty chain and hangs indefinitely. Disable
pipelining the same way community.general.machinectl already does.
Also add tests/unit/plugins/become/test_machinectl.py mirroring the
existing test_run0.py. machinectl had no unit test coverage before,
which is why CI did not catch the SYSTEMD_COLORS=0 prefix change
when the equivalent run0 change broke test_run0_basic/test_run0_flags.
