avformat/argo_cvg: Avoid relocations for ArgoCVGOverride

Browse Source 
The average length of the strings used here does not differ much
from the length of the longest string; therefore it makes sense
to use an array big enough for the longest string and not
a pointer to a string. This also moves this array into .rodata
(from .data.rel.ro).
