pkg thinks kernel is old

[Bengt Ahlgren]

I've ran into this on my 11.3-STABLE system:

# uname -K
1103500
# pkg update -f
Updating ivyp repository catalogue...

Newer FreeBSD version for package zziplib:
To ignore this error set IGNORE_OSVERSION=yes
- package: 1103000
- running kernel: 1102509
Ignore the mismatch and continue? [Y/n]: 

I build my own packages with poudriere, and have just switched from an
11.2-REL to an 11.3-REL jail.  I didn't force-upgrade everything after
the switch, perhaps that's needed to make pkg recognise the correct
kernel version?
