Subject: [PATCH 20/24] ver_linux: kbd_console-tools.patch

'loadkeys -h' no longer prints the version number across all distros,
despite the claim to do so in the manpage, which I found to be the case
on a Debian Linux system.

The proposed implementation utilises the output of 'loadkeys -V' to
acquire the version of both 'Kbd' and 'Console-tools'.

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
