scheduler: import traceback

[aderumier]

if a script in /etc/network/ifup.d/ is segfaulting,

on config loading (ifup -a), ifupdown2 is stopping

ifup -a
"
info: executing2 /etc/network/if-up.d/postfix
debug: lo: up : running script /etc/network/if-up.d/resolved info: executing2 /etc/network/if-up.d/resolved
error: name 'traceback' is not defined
debug: saving state ..
info: exit status 1
"

with this fix:

debug: lo: up : running script /etc/network/if-up.d/resolved info: executing2 /etc/network/if-up.d/resolved

@julienfortin thanks!
(proxmox8 has been released with last ifupdown2 version, so I begin to see bug reports, so maybe I'll have other patches soon ^_^)

[julienfortin]

@aderumier sounds good, thanks for always sending your patches! I know I still have a few to review/merge. 😅

I should have more users return about my ipv6 slaac soon. (the patches are already applied in proxmox ifupdown2 packages)
