go_android_exec gets the exit status of the process run inside the Android emulator by sending a small shell script that runs the desired command and then prints "exitcode=" followed by the exit code. This is necessary because adb does not reliably pass through the exit status of the subprocess. An old bug about this (https://code.google.com/p/android/issues/detail?id=3254) was closed in 2016 as fixed in Android N (7.0), but it seems that the adb on the Android builder at least still sometimes fails to pass through the exit code. Unfortunately, this workaround has the effect of injecting "exitcode=N" into the output of the subprocess it runs, which messes up tests that are looking for golden output from a subprocess. Fix this by inserting a filter Writer that looks for the final "exitcode=N" and strips it from the exec wrapper's own stdout. For #15919. This will help us in cleaning up "host tests" for #37486.
