Use Common paths for Build, Publish and Pack

The new Output paths point to...

Build: `~build\{bin,obj}`
Restore: `~build\ext`
Publish: `~publish\...`
Pack: `~packages\{bin,obj}`

with-in the repository root directory.

Also, Fix logic in Update-Header.ps1 to exclude new paths
from the list of sources files that works across platforms.
