contrail-version output for contrail-vrouter is not properly formatted. ...

...The current output is

root@a3s6:~# contrail-version
Package                                Version                 Build-ID | Repo | Package Name

Fix the width for display of version and build-id, so that we get the following output (This is required for correctly
exporting version information for vrouter in UVE)

Package                                Version                       Build-ID | Repo | Package Name
