fix for incorrect pkg-plist (multimedia/gdvrec)

[Henri Michelon]

Hi All,

Due to the 'pkg-plist strict enforcement' my port multimedia/gdvrec need a quick
fix before being marked BROKEN. A PR, ports/75293, have been send one month ago
with the fix, and if somebody want to commit it quickly he/she will be rewarded
! I will give you... tout ma gratitude ;)

Thanks
Henri Michelon
