[master]: Move flex.pdf to the flex-doc package.

This makes it possible for the flex package's contents to not change
if texinfo is not installed, e.g. in the stage1 build profile.

[master]: Build dependency fixes, no code change

Added a missing build depends on vm-super-minimal, reuired fro building
the pdf documentation, (Closes: #752151).

Move flex.pdf to the flex-doc package. This makes it possible for the
flex package's contents to not change if texinfo is not installed,
e.g. in the stage1 build profile.  Thanks to Peter Pentchev

Move the flex-doc build dependencies to B-D-I. Move the TeX Live
dependencies to Build-Depends-Indep and only build the HTML and PDF
documentation if actually requested. This breaks a circular build
dependency by not requiring texlive for the build of the arch-dependent
flex binary packages.  (Closes: #749344).
