Allow overriding symbol visibility.

Fontconfig symbols were hardcoded to be either hidden or exported.  This patch
adds configurable symbol visibility.  This is useful for projects that want to
do in-tree fontconfig builds and not export any symbols, otherwise they would
conflict with the system library's symbols

Chromium is a project that does in-tree fontconfig builds, and the workaround
currently used is "#define visibility(x) // nothing" [1] and building with
"-fvisibility=hidden".
