[wwwdocs] Remove XHTML logo from footer and save space

[Gerald Pfeifer]

This was inspired by Mike, though he probably doesn't know it. :-)

Remove the XHTML button from the standard footer and merge the Last
Modified line with the first line, saving a fair amount of space.

For those inclined, the dot at the end of the first line still links
to the validator. :-)

Live on gcc.gnu.org.
