Parse event log on Android 8

[Mikhail Lopatkin]

Sony Xperia XZs, Android 8.0.

Event log cannot be enabled (there is no checkbox).

Fixed in latest snapshot

Not fixed actually

Works on Pixel 2 (8.1.0). That suggests that this may be device-specific problem.

No longer reproducible (0.19-SNAPSHOT build 16)

Damn it, Sony

The issue isn't reproducible immediately after boot. But after that

$ adb shell 'logcat -b events -s -d  > /dev/null || echo 0'
Warning: leftover binary log data (1 bytes)
Warning: leftover binary log data (1 bytes)

It writes warnings to stderr, and this breaks error code reader. The latter most likely assumes that non-empty input means error.

Fix #128: Be tolerant to logcat's stderr output when checking buffer

This may not indicate a error but a mere warning. Return code is checked for error.
