man-pages PDF book's an.tmac

Hi,

We have a huge an.tmac copy in the Linux man-pages scripts, for
generating the PDF book.

	$ wc -l scripts/LinuxManBook/an.tmac 
	1611 scripts/LinuxManBook/an.tmac

However, it's mostly identical to groff-1.23.0's an.tmac.

	$ diff -u1 -w scripts/LinuxManBook/an.tmac /usr/share/groff/1.23.0/tmac/an.tmac

I was wondering if we need to keep it, or if we could remove it, or at
least trim it to just a few lines.  Maybe some things can be upstreamed,
or maybe they are already upstream.

Thanks,
Alex
