Description

This PR fixes the build-and-test(-differential) CI for the Agnocast case.

There were multiple issues:

• The env var was mistakenly named AGNOCAST_ENABLED but was supposed to be ENABLE_AGNOCAST. As a result, even the Agnocast case did not build/test with Agnocast, hiding potential issues.
• Agnocast kmod and heaphook were not installed when Agnocast was enabled
• The LD_PRELOAD and AGNOCAST_MEMPOOL_SIZE env vars were not being set
