Valentin Rothberg d2ac85f7aa install sigproxy before start/attach
Install the signal proxy before attaching to/starting the container to
make sure there's no race-condition as revealed in the failing start/run
tests in #16901.  The tests had the valid expectation that signal
forwarding works once the container is running.

Further update the tests to account for the attach test where the
expectation is that signal forwarding works once Podman has attached to
container (or even before).

Fixes: #16901
