Description

Android libc(bionic) does not have timespec_get until recently. So, it is better to exclude using it just like how mac build is configured to be.

How to reproduce

A simple build on android using ndk, reproduces this issue. I could fix it using this:
sed -i 's/#ifdef __APPLE__/#if defined(__APPLE__) \|\| (defined(__ANDROID__) \&\& __API_LEVEL__ < 29)/g' src/rdtime.h

IMPORTANT: Always try to reproduce the issue on the latest released version (see https://github.com/edenhill/librdkafka/releases), if it can't be reproduced on the latest version the issue has been fixed.
