[patch] Use "($cmd)" in place of "$(cmd)" in gendocs.sh

[Ben Pfaff]

I noticed this bug by inspection.  That is, I didn't actually try
to format DocBook either with or without it, so it's possible
that for some weird reason it makes sense to use command
substitution here.  But I doubt it.

(I seem to recall signing copyright papers for Texinfo a number
of years ago when I was tentatively planning to do some work on
it that I never got around to doing.)

        * util/gendocs.sh: Use "($cmd)" in place of "$(cmd)" where
        command substitution is not desired.
