configure.ac: Make it possible to build on Android Termux
The recent Termux's clang predefines `__ANDROID_API__` as a fixed number
24. However, when it is lower to the current device version, some
functions that "configure" detemines available are not declared
correctly in the header files.
This change forces to overwrite the predefined `__ANDROID_API__` macro
with the current device version.
