need to set EPOCH due to the version change. Switches the port to MODGO_MODNAME to fetch the modules needed, dropping the BDEP on net/go-net. godoc doesn't need hacks now to be built, but gopls is not included anymore: it's provided by new devel/gopls port. While here sync DESCR with reality and fold long lines, update HOMEPAGE and drop redundant MODGO_TYPE=bin. tested by Laurent Cheylus (thanks!) ok sthen@
