In a systemd unit dollar and percent signs are used for variables. A backslash
is used for escape sequences. If any of these characters are used in the create
command we have to properly escape them so systemd does not try to interpret them.

Fixes #9176

The unit generation accidentally escaped the %t in the pod id file path.
This is a regression caused by containers#9178. This was not caught by the tests
because the test itself was wrong. It used a full path instead of the
systemd variable %t like the actual code does.

Fixes containers#9373
