[vdr] Stop ScanVideoDir from traversing too much

[Jaakko Hyvätti <jaakko@hyvatti.iki.fi>]

  Hi Klaus,

  When I have the file size maximum set at 100 MB, this creates a lot of
files.  Traversing 100 GB of these files means that a 60 second watchdog
will restart vdr.  To prevent that, the following prevents traversing .del
directories when we are searching for .rec and vice versa.  This cuts the
time needed to a couple of seconds.

  Could this be included in 1.3?
