Subject: Rebuild to split out IPA files to libcamera-ipa.

When stripping the IPA shared objects, they need to be re-signed.
Split out IPA files so we can manually strip and re-sign.
NOTE: The signature files are required (although this unfortunately makes the package unreproducible :( ).
Add missing depends to libcamera an libcamera-tools.
