access/file: don't read-ahead when processing remote contents (closes #9885, refs #8446)

OS X Mavericks takes read-ahead very seriously when accessing SMB drives, so it caches up to a 100 MB. However, when the end of said cache is reached, VLC will stutter because the file system needs to re-connect to the server first. Disabling read-ahead leads to a continous data flow at the media's bitrate.
