Add SHIFT6m to hardware bitmap blocklist

[johan12345]

I received the following stacktrace from a user with a SHIFT6m device running Android 8.1 (API 27). This is not in a shared element transition.

Are you sure this isn't a shared element transition? It looks like the stacktrace calls androidx.transition.TransitionUtils.createViewBitmap(TransitionUtils.java:133), which will fail on API 27 due to requiring a software bitmap.

Just to confirm: the crash is only occurring for users with that device model? There are no reports for other devices?

[johan12345]

It is a transition implemented by the StfalconImageViewer library, but as far as I can see It's just using transitions within a view using TransitionManager for that, not the shared element transition API (i.e. between different fragments/activities, using addSharedElement).

It's the first report about this crash that I've received so far, and the code has been unchanged since a release on 1 April this year... I also couldn't reproduce it on an API 27 emulator.

@johan12345 Gotcha, given this device fits the pattern of devices that could have this problem and disabling hardware bitmaps for this device is low risk (it's at most a minor perf hit), let's merge this in.
