Remove ares_build.h from git; it seems to be causing problems on Travis.

-/*
- * NOTE 1:
- * -------
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * c-ares library user nor by the c-ares library builder.
- *
- * If you think that something actually needs to be changed, adjusted
- * or fixed in this file, then, report it on the c-ares development
- * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
- *
- * Try to keep one section per platform, compiler and architecture,
- * otherwise, if an existing section is reused for a different one and
- * later on the original is adjusted, probably the piggybacking one can
- * be adversely changed.
- *
- * In order to differentiate between platforms/compilers/architectures
- * use only compiler built in predefined preprocessor symbols.
- *
- * This header file shall only export symbols which are 'cares' or 'CARES'
- * prefixed, otherwise public name space would be polluted.
- *
- * NOTE 2:
- * -------
- *
- * Right now you might be staring at file ares_build.h.dist or ares_build.h,
- * this is due to the following reason: file ares_build.h.dist is renamed
- * to ares_build.h when the c-ares source code distribution archive file is
- * created.
- *
- * File ares_build.h.dist is not included in the distribution archive.
- * File ares_build.h is not present in the git tree.
- *
- * The distributed ares_build.h file is only intended to be used on systems
- * which can not run the also distributed configure script.
- *
- * On systems capable of running the configure script, the configure process
- * will overwrite the distributed ares_build.h file with one that is suitable
- * and specific to the library being configured and built, which is generated
- * from the ares_build.h.in template file.
- *
- * If you check out from git on a non-configure platform, you must run the
- * appropriate buildconf* script to set up ares_build.h and other local files.
