Fix type confusion in guc_var_compare()
Before this change guc_var_compare() cast the input arguments to
const struct config_generic *. That's not quite right however, as the input
on one side is often just a char * on one side.
Instead just use char *, the first field in config_generic.
This fixes a -Warray-bounds warning with some versions of gcc. While the
warning is only known to be triggered for <= 15, the issue the warning points
out seems real, so apply the fix everywhere.
