meson: Require 0.54.2 when building for Android ≤ 20

Browse Source 
cc.has_function() provide false positive for Android-20 and earlier; the fix is in Meson 0.54.2. People attempting to cross-compile previously wouldn’t have been able to get it to work without manual intervention, so the dependency bump for this platform is not an additional obstacle for them.
