test(android): drop the retired installArgs from the install-timeout fixture

`2cafab3ad0` typed this fixture as `AndroidSnapshotHelperManifest` while carrying `installArgs`, a
field the manifest no longer has: #2603 retired the `-t` flag the array used to spell, the helper now
installs with a fixed `adb install -r`, and the parser ignores the key on older blobs — which is what
`snapshot-helper.test.ts` pins. The literal therefore failed `pnpm typecheck` with TS2353 on every
branch, reding `Typecheck & Package` on `origin/main` itself.

Nothing read the key. The install path builds its adb arguments from the provider's own `replace`
option, and the assertion this fixture serves is about the timeout hint derived from the adb failure.
