add linuxcnc-uspace manpage build deps to control.top.in

The manpages go in linuxcnc-uspace.deb (not in linuxcnc-doc-en), so they
are built with the architecture-dependent ("binary") debs.

Since some manpages are written in asciidoc rather than roff, these
build dependencies are needed in Build-Depends (which is satisfied for
both architecture-dependent and architecture-independent builds), not
just in Build-Depends-Indep.
