jade e715e5fd31 releng: fix logging inside interactive xonsh
I don't know when this broke, it seems like it happened since the 24.05
upgrade, so xonsh 0.15.

What happened is that xonsh was trying to intercept log output, which
explodes if you have the logger survive past one command input. This is,
however, impossible to avoid if you are trying to use logging when you
import releng from inside xonsh for interactive use!

The error below is because the memory handler backing the stdout/stderr
of the one command that's just been run was closed after the command
completed.
