[cairo] [PATCH 2/3] Update README with new minimum MacOSX requirements

[Andrea Canciani]

From: Andrea Canciani <ranma42 at tartaros.local>

Since 70cc8f250b5669e757b4f044571ba0f71e3dea9e the quartz backend is
using some APIs that are not available on MacOSX 10.4 directly
(i.e. without detecting their availability through dynamic linking).
This means that the quartz backend does not work anymore on MacOSX
10.4 and that the 10.5 SDK (or newer) is needed to build.
