include/package-pack: add missing apk package lifecycle events

- pre-install calls preinst
- pre-upgrade calls preinst with PKG_UPGRADE=1
- post-upgrade calls postinst with PKG_UPGRADE=1
- prerm and postrm from the previous version of a package are NOT
  executed on upgrade, so packages are expected to handle their own
  migrations in the new versions
