bookmark: add pushkey hook compatiblity to the bundle2 part

Currently, pushing a bookmark update triggers a pushkey hooks. It is likely
that users in the wild use such hooks to control bookmark movement. Using a non
push-key mechanism to exchange bookmark means these hooks are no longer called,
possibly breaking existing users setup. So we add explicit call to the pushkey
hooks in the handling of the bundle2 part. This behavior can be disabled with a
new config knob: 'server.bookmarks-pushkey-compat'.
