Display micro and build version of the guest tools

[stormi]

The version of the guest tools currently displayed in the General and the Advanced tabs of a VM only contains major and minor numbers.

It would be good to have the full version in the Advanced tab, and probably in the General tab too to be consistent.

The new version displayed would then be major.minor.micro-build (dash before build because it's not exactly part of the upstream version, but is still useful information especially in XCP-ng context where we'll use that number to identify the tools version more precisely).

It would be changed here:
