fix(test): fix the failed ASan test for gutil due to absl::node_hash_map

[empiredan]

#2344.

The internal types used by absl::node_hash_map have different layouts when
compiled with ASan versus non-ASan builds. As a third-party dependency, Abseil
is always built in non-ASan mode. However, when Pegasus is built with ASan enabled,
Abseil headers are also compiled under ASan, which leads to a mismatch between the
header-compiled structures and the Abseil library itself, causing ASAN tests to fail.

Possible solutions include:

1. When third-party dependencies change, also build those third-party libraries with
   ASan enabled for ASan builds.
2. When building third-party images, additionally produce a separate ASan-based
   image, which can be used by ASan CI workflows when third-party dependencies
   themselves have not changed.
