make: revert switch to 'go install'
go install acts incredibly weirdly and rarely does what you want, not to
mention that it's just bad for distribution build setups. Switch back to
go build, which works properly and doesn't have half as many issues.

Fixes: 6c9628cdb1 ("Build and install from GOPATH")
