Adapt call() on ContentProvider for Android 11

Browse source 
This commit in AOSP framework_base added a parameter "attributionTag" to
the call() method:
12ac3f406f%5E%21/#F17

As a consequence, the method did not exist, so scrcpy used the legacy
call() method (using the authority "unknown") as a fallback, which fails
for security reasons.

Fixes #1468 <https://github.com/Genymobile/scrcpy/issues/1468>
