go: Reset unneeded GOARCH variables for native recipe
These variables depend on TUNE_FEATURES variable and that creeps into
dependencies for native as well as a result, which means go-native gets
recompiled everytime machine/arch is changed.
Fixes sstate differences found e.g.
basehash changed from
600fb6be571fa4853232a7fed78945ee19b324e54b1b94cff93ef472b6290103 to
994de861190a56064d3e186d9c411152127e230bf2f77b17e59b2c5932a41249
List of dependencies for variable TUNE_FEATURES changed from '{'TUNE_FEATURES_tune-core2-32', 'DEFAULTTUNE'}' to '{'TUNE_FEATURES_tune-armv7vethf-neon', 'DEFAULTTUNE'}'
changed items: {'TUNE_FEATURES_tune-core2-32', 'TUNE_FEATURES_tune-armv7vethf-neon'}
