Use pkg-config for detecting libpng and libbz2 also.

* builds/unix/configure.raw (HAVE_PKG): New variable.
Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.
Search for libpng using `pkg-config'.
Fix definition of `LIBHARFBUZZ' variable.
* builds/unix/freetype-config.in ($libs): Updated.
* builds/unix/freetype2.in: Add `URL' field.
Update `Requires.private' and `Libs.private'.
* builds/unix/unix-def.in: Updated.
