cmcurl: Backport curl bug 1192 fix (#14250)

LLVM headers define strlcat as a macro rather than as a function.
See upstream Curl issue:

 http://curl.haxx.se/bug/view.cgi?id=1192

It was addressed by removing use of strlcat altogether.  Port the
upstream fix to CMake's curl.

- * nating the result.
- *
- * The strlcpy() and strlcat() functions return the total length of the
- * string they tried to create.  For strlcpy() that means the length of src.
- * For strlcat() that means the initial length of dst plus the length of
- * src. While this may seem somewhat confusing it was done to make trunca-
- * tion detection simple.
