ENH: allow -pkg|-package option for wmakePrintBuild

- improves the chances of tracking who built OpenFOAM, where, etc

ENH: make it easier to parse version/build from OpenFOAM -help output

- For example,
    foamListTimes -help | awk '{ if (/^Using:/) print $2}'
    foamListTimes -help | awk '{ if (/^Build:/) print $2}'
