go: reduce package size by stripping binaries and removing pkg
A very long time ago strip didn't always work well on Go binaries, but this has
been fixed for almost a decade[1], so there is no need to keep this.

Just the standard strip hook won't work, as it will try (and fail) to strip
files in testdata and some other things. You can add nostrip_files, but that
would be a long list.

This also removes the pkg/linux_arch directory from the installation. This is a
pre-compiled cache of the standard library, and isn't really needed. The only
downside of not installing it is that the first compile will take a few seconds
longer (after which it's in the cache), and since the Go compiler is fairly fast
it's not a big deal IMO.

Alternatively, only pkg/cmd could be removed. This contains the cache for the go
command and "go tool [..]" commands, but you can never import this as it's all
"package main", so it's a useless cache AFAIK. It's also the biggest contributor
to the size.

Comparison of sizes (each one relative to the previous one):

	current       Package:   111M         Installed: 369M
	rm pkg/cmd    Package:    90M (-21M)  Installed: 268M (-101M)
	strip         Package:    62M (-28M)  Installed: 236M (-32M)
	rm pkg        Package:    45M (-17M)  Installed: 158M (-78M)

So that's a total saving of 66M in the package size, and 211M for the installed
size.
