test(android): read the install-timeout fixture from the helper manifest fixture

#2618 removed `installArgs` from `AndroidSnapshotHelperManifest` and updated the shared helper
fixture, the packaging script and the parse test, but this file kept its own hand-written manifest
literal with the field still in it, which is what `tsc` rejects on main today's tip: an excess
property on a type that no longer declares it. A second copy of the manifest is also how that field
survived this long.

Both tests re-hash the manifest for the APK they write, so the identity fields carry no test
intent; they now come from `ANDROID_SNAPSHOT_HELPER_FIXTURE_ARTIFACT` like every other helper test.
The one case that still needs a manifest carrying `installArgs` is the parse path that ignores it,
and that case spells the key out inline in `snapshot-helper.test.ts`.
