avutil/opt: Fix AV_OPT_TYPE_CONST default value 

It uses the int64_t instead of the double member.

(This code can currently not be reached: av_opt_get() calls
av_opt_find2() with NULL as unit in which case AV_OPT_TYPE_CONST
options are never returned, leading av_opt_get() to always
return AVERROR_OPTION_NOT_FOUND when searching for AV_OPT_TYPE_CONST*.
For the same reason the code read_number() will never be called
from get_number() when searching for an option of type
AV_OPT_TYPE_CONST. The other callers of read_number() also only
call it with types other than AV_OPT_TYPE_CONST.)
