GN: build skiaserve
I trimmed the libmicrohttpd sources and defines down to the minimum needed to build and run. This builds and runs on Linux and Android for me.
Request.h was missing an include for SkTypes.h, which supplies the default for SK_GPU_SUPPORTED if not otherwise defined.
To build on Android, exit() -> _exit().
build.py was unused.
