  1. fuzz_targets: update list of fuzzers 

    That list is used by oss-fuzz, and probably somewhere else. Add
the new altsvc, base64 and doh fuzzers to it.

  2. fuzz_{base64,doh}: curl lib includes for standalone harnesses 

    This patch adds `-I` flag to compilation flags for
standalone harnesses in Makefile.am.
Variable CURLDIR is used to determine include path.
This patch sets CURLDIR envvar in ossfuzz.sh, but name is taken
from mainline.sh.
That makes dependencies work with oss-fuzz.
It should also make it work with mainline.sh
