Fix the following -Wcast-qual warnings in usr.sbin/sa/db.c:

usr.sbin/sa/db.c:82:20: error: cast from 'char const (*)[9]' to 'void *' drops const qualifier [-Werror,-Wcast-qual]
key.data = (void*)&VERSION_KEY;
^
usr.sbin/sa/db.c:178:20: error: cast from 'char const (*)[9]' to 'void *' drops const qualifier [-Werror,-Wcast-qual]
key.data = (void*)&VERSION_KEY;
^

Replace the VERSION_KEY define with a writable char array, so no const
qualifier needs to be dropped anymore.
