Makefile: lock jsonnet-bundler version

The new version (v0.3.1) of jsonnet bundler causes some changes
to go.mod and jsonnetfile.json.  The build should 'go get' a
specific version instead of the latest to prevent new releases
from breaking existing builds.

Adjust Alertmanager inhibit conditions

Change deprecated BaseImage to Image
