[PATCH] ver_linux: add comparison with required version and colour to output

Add the required version from changes.rst.
Add code for comparison and print in colour (blue, green, red) depending
on the result of the comparison.

I had this patch on my mind for more than half a year. I was convinced I
couldn't do it because awk is such a special language. Took me less than
an hour without AI - WTF

Somehow I messed up the formating of the output. I guess it's this lines
+		ofmt = "%-20s\t%s\n"
but I couldn't figure it out :(
