Revert "has: generate the curl/has.h header"
This reverts commit a60bde79f9adeb135d5c642a07f0d783fbfbbc25 I have pushed by mistake. Apologies for my incompetent use of the git repo!

+# Experience has shown that the symbols-in-versions file is very useful to
+# applications that want to build with a wide range of libcurl versions.
+# It is however easy to get it wrong and the source gets a bit messy with all
+# the fixed numerical comparisons.
+#
+# The point of this script is to provide an easy-to-use macro for libcurl-
+# using applications to do preprocessor checks for specific libcurl defines,
+# and yet make the code clearly show what the macro is used for.
+#
+# Run this script and generate libcurl-symbols.h and then use that header in
+# a fashion similar to:
+#
+# #include "libcurl-symbols.h"
+#
+# #if LIBCURL_HAS(CURLOPT_MUTE)
+# has mute
+# #else
+# no mute
+# #endif
+#
