7a777ec build: Fix `make apk` if ccache enabled (Hennadii Stepanov)

Pull request description:

  On master (456c8d6) `make apk` is broken for Android targets if the build system was configured with `--enable-ccache` explicitly or by default.

  This PR fixes this bug, and enables `ccache` for "ARM64 Android APK" Cirrus CI job.
