container: increase podman stop timeout

The default timeout for 'podman stop foo' is 10 seconds, which for
heavily loaded systems with intricate shutdown process is *waaaay*
too short.  Increase it to the container script default 30s, which
coincidentally is also the container@.conf template's kill delay.

Fixes #1149
