Release Notes "Supported Platforms" section should be in sync with README.md

README.md in it's "Building BIND" section mentions that libuv (9.15 and newer) and libcap are required (in some way/sense) for BIND to build: BIND also requires the 'libuv' asynchronous I/O library [...] On Linux, BIND requires the 'libcap' library to set process privileges, though this requirement can be overridden [...].

None of these is mentioned in the Release Notes "Supported Platforms" section, but it probably should as those two sections cover the same ground, though probably for different audiences.
