Fix android build for 4.x

[TomMahle]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-track-player@4.1.2 for the project I'm working on.

Android builds are currently broken in 4.1.2. The fix is based on this post

Here is the diff that solved my problem:
