avcodec/svq1enc: Move initializing DSP out of svq1enc.c

Browse Source 
Otherwise svq1enc.o gets pulled in by the svq1encdsp checkasm
test and it in turn pulls the rest of lavc in.
Besides being bad size-wise this also has the downside that
it pulls in avpriv_(cga|vga16)_font from libavutil which are
marked as being imported from another library when building
libavcodec as a DLL and this breaks checkasm because it links
both lavc and lavu statically.
