ci: use v1 ClusterFuzzLite images

The ubuntu-22.04 runner pin did not resolve PR fuzzing failures. Jobs
still fail in build_fuzzers with Docker API mismatch:
client 1.41 vs daemon minimum 1.44.

Switch ClusterFuzzLite actions back to the maintained v1 image path and
align the local symbolizer helper image with that runtime.

Refs #84.
