goprocess: use debug/buildinfo on Go 1.18 and newer
52f666a 
Use package debug/buildinfo [1] introduced in Go 1.18 [2] when possible.
This should avoid previous issues with rsc.io/goversion where Go
processes were no longer listed.

I think #166 should fix this issue, at least when building gops using Go 1.18.

@raochq could you please check whether gops built from latest master branch using Go 1.18 works as expected for you?

I only have this problem once. It never happened again。
