Bug#755818: xbmc-pvr-addons: spurious build-dependencies on libavcodec-dev

[Andreas Cadhalpun]

Source: xbmc-pvr-addons
Version: 13.0+git20140512+g91cc731+dfsg1-1
Severity: normal

Dear maintainer,

Starting with version 13 xbmc-pvr-addons doesn't use libavcodec any 
more. The checks for it were removed from configure.ac.

Therefore please remove the now unnecessary build-dependency on 
libavcodec-dev.

Best regards,
Andreas
