Don't invoke XT_ENABLE_XTC_REGISTER from XT_SETUP: this sets the variable immediately, which makes it difficult to check later if the option was specified or not.

XT_ENABLE_XTC_REGISTER is now invoked from XT_CHECK_XTC, but only in
if the variable xt_xtc_register was not set yet.

Maybe still a bit fragile, but I think this is finally the right way
to enable/disable xtc.
