[Impeller] no-op fragment program on Android until it works. (flutter#43657)

The framework has switched into mat3 by default, which means the fragment program ink sparkle has replaced the default ink splash. Since this is not implemented, all of the impeller benchmarks are crashign.

No-op this so we at least get benchmark numbers until its implemented.
