package/go: adjust comments

Browse Source 
Adjust comments in the Go package to improve clarity:

Config.in.host:

 - Add comment mentioning list of supported architectures.

go.mk:

 - Reword comment re: copying src/ to host/
   - the previously linked issue is not relevant.
   - instead: mention that src/ is needed for stdlib.
 - Adjust comment re: adjusting file timestamps.
   - mention this is needed to avoid rebuilding stdlib
