project/generic-arm64-fuzz: Increasing IPC_MAX_HANDLES for coverage tests
Increasing IPC_MAX_HANDLES from 64 to 128 when compiling targets with
coverage enabled.
This was needed because we had more than 64 connections to
com.android.trusty.coverage.aggregator.
Bug: 258572142
Test: AppMgrWaitForPort suite on arm64 fuzz target
