libports: add CCID library

[cproc]

The CCID library provides a driver for USB smartcard readers using the CCID protocol. It is used by the pcsc-lite library (separate issue).

When the CCID library is built, it creates a file 'Info.plist' in the 'bin' directory, which contains information about the supported card readers. This file is loaded by the library at runtime as '/ifd-ccid.bundle/Contents/Info.plist' and can be made accessible at this location in the VFS configuration of the application:

<config>
    <libc>
        <vfs>
            <dir name="ifd-ccid.bundle">
                <dir name="Contents">
                    <rom name="Info.plist"/>
                </dir>
            </dir>
        </vfs>
    </libc>
</config>
