Subject: [PATCH] Fix build on macOS

macOS has no cups.pc, so the pkg-config calls in module.mk expand to
nothing and the build fails (see #3). The raster API also lives in libcups
itself, so -lcupsimage is not needed.

On Darwin:
- use cups-config for compiler/linker flags and CUPS directories
- look for jbigkit in Homebrew (Apple Silicon and Intel) and MacPorts,
  overridable with JBIGDIR
- honour ARCHFLAGS, e.g. ARCHFLAGS="-arch arm64 -arch x86_64" for a
  universal binary

Other platforms are unchanged.
