cbfs: add cbfs_read()

Allow for reading from cbfs media without having a handle
    to a non-CBFS_DEFAULT_MEDIA cbfs_media. In conjunction with
    cbfs_locate_file() one can locate and cbfs_read() a file
    without bringing the entire file through a potentially
    temporary buffer (non-memory-mappable cbfs media platforms).
