imagebuilder: fix multiple issue with manifest and sign keys handling

Fix multiple issue with manifest handling where APK was hardcoded
and fix a logic error where (TODO) APK _check_keys was called for the
OPKG codepath instead of correctly calling for the APK codepath.

Fixes: d788ab376f85 ("build: add APK package build capabilities")
