Do not install host snapshot modules with existing prebuilts.

Host fake snapshot includes a prebuilt attribute for a host module
that already contains a prebuilt version in the source tree.  When
installing the host snapshot ignore any modules that already contains
a prebuilt version.

Bug: 225890931
Test: m HOST_FAKE_SNAPSHOT_ENABLE=true host-fake-snapshot dist
Test: install fake snapshot with update.py and validate prebuilt modules are not included
