Prior to this commit CGO was used in OpenBSD implementation of
Process.CmdlineSliceWithContext() for parsing the "kern.proc.args"
sysctl output. It requires some pointer arithmetics and raw pointer
dereferencing.
Having CGO in the "process" module prevents it from being go vet'ted
on any platform other than OpenBSD. In order to overcome this
limitation, the sysctl output parsing was reimplemented without raw
pointer deferencing. The resulting code might be slightly slower
than the original one, but it is cleaner and safer.
Since this fix allows go vet with GOOS=openbsd to run without any
issues on all platforms, openbsd entries were also added to the "vet"
Makefile target.

This enables using gopsutil in a codebase that gets built on other OSes
than the ones supported. Instead of a build failure as before, due to
the build tags, gopsutil will now throw an "not implemented" runtime
error.
Fixes#234.
