c90457a95e lavc/svq3: Fix regression decoding some files. 
Fixes some SVQ3 encoded files which fail to decode correctly after 6d6faa2a2d.
These files exhibit lots of artifacts and logs show "Media key encryption is not implemented".
However they decode without artifacts before 6d6faa2a2d.
The attatched patch allows these files to successfully decode, but also reject media key files.

Tested on the files in #6094 and http://samples.mplayerhq.hu/V-codecs/SVQ3/Vertical400kbit.sorenson3.mov

c50dc77ac7 configure: add LIBDRM to extralibs_avutil 
When static linking programs using ffmpeg libraries, if linking against
libavutil, -ldrm is listed before -lavutil. This leads to linking failure
due to undefined reference of drmGetVersion() and drmFreeVersion().
This is why when pkg-config create libavutil.pc doesn't append -ldrm
after -lavutil.

Create LIBDRM=-ldrm in case libdrm is enabled and add $LIBDRM to
extralibs_avutil.
