Remove NS_BLOCK_ASSERTION trick from packages?

[defagos]

We had to add a NS_BLOCK_ASSERTION flag to circumvent an issue I reported to Apple.

This issue might be fixed and if this is the case this trick might not be needed anymore. All SRG library package manifesets should be updated in this case.

Tested with Xcode 13.2.1. Not fixed yet, workaround is therefore still needed.
