add Android NDK r27c

[kambala-decapitator]

Summary

Changes to recipe: android-ndk/r27c

Motivation

Adds the latest available NDK version

Details

The update is highly desired because CMake projects declaring minimum version < 3.3 can't be built using r27 due to https://github.com/android/ndk/issues/2032 which was fixed in r27b
