scummvm: update to 2.7.1

Upstream changelog:

* Added ScummVM Log file viewer, so you can easily report the problems on platforms with limited file access, e.g. Android, iOS or even modern Windows.
* Fixed the shader-based scaler loading on some platforms.
* Added multiple improvements to AGI, AGS, Cryomni3D and 12 more engines.
* Improved the detection of Broken Sword 1 & Broken Sword 2, so more original versions get properly detected
