configure: fix recv/send/select detection on Android

This reverts commit d4f25201fb7da03fc88f90d51101beb3d0026db9.

The overloadable attribute is removed again starting from
NDK17. Actually they only exist in two NDK versions (15 and 16). With
overloadable, the first condition tried will succeed. Results in wrong
detection result.

Closes #3484
