[Android] Fix CPU architecture mismatch causes crash in crosswalk runtime

In runtime, it will try to get the version of runtime library
before using runtime view. Which causes crash if CPU arch mismatches
for crosswalk native library.
Fix this by stop executing to avoid crash after detected CPU arch
mismatch.
