tcmode-default.inc: drop preferred version of gzip-native

* gzip was recently upgraded from 1.8 to 1.9, now all the builds show:
  NOTE: preferred version 1.8 of gzip-native not available (for item gzip-native)
  NOTE: versions of gzip-native available: 1.9
* drop the setting, because nobody is probably going to use older
  gzip-native than 1.4 when there is only 1.9 available in oe-core
