Add github.com/shirou/gopsutil/host to vendor

This is needed for a coming PR to measure system uptime.
I separated vendor changes out, because they are larger while easier to
review.

This done via:
GO111MODULE=on go get github.com/shirou/gopsutil/host
GO111MODULE=on go mod vendor

+About w32
+==========
+
+w32 is a wrapper of windows apis for the Go Programming Language.
+
+It wraps win32 apis to "Go style" to make them easier to use.
+
+Setup
+=====
+
+1. Make sure you have a working Go installation and build environment, 
+   see this go-nuts post for details:
+   http://groups.google.com/group/golang-nuts/msg/5c87630a84f4fd0c
+   
+   Updated versions of the Windows Go build are available here:
+   http://code.google.com/p/gomingw/downloads/list
+   
+2. Create a "gopath" directory if you do not have one yet and set the
+   GOPATH variable accordingly. For example:
+   mkdir -p go-externals/src
+   export GOPATH=${PWD}/go-externals
+
+3. go get github.com/AllenDang/w32
+
+4. go install github.com/AllenDang/w32...
+
+Contribute
+==========
+
+Contributions in form of design, code, documentation, bug reporting or other
+ways you see fit are very welcome.
+
+Thank You!
