nit: prefer not having a negative condition or adding to sources, and instead
subtracting from sources (similar to the gcm_driver and test_support targets)
and swapping condition.

if (is_android) {
sources -= non-android files
} else {
sources -= android files
}

This was done as part of https://codereview.chromium.org/1418543006. Either way,
agreed & changed.
