Make print/tex-dvipsk a runtime dependency.

Two reasons for this:
1. Document builds can fail without it even when using pdftex.
   From dblatex -d -D:

   Build uwm-pc-user-guide.pdf
   pdflatex failed
   Unexpected error occured
   Traceback (most recent call last):
   File "/usr/local/lib/python2.7/site-packages/dbtexmf/core/dbtex.py", line 332, in compile

   From tail -n 11 /tmp/tmpe0bJK0/uwm-pc-user-guide.log:

   Here is how much of TeX's memory you used:

   !pdfTeX error: pdflatex (file 8r.enc): cannot open encoding file for reading
   ==> Fatal error occurred, no output PDF file produced!

2. dvips is a valid backend to specify with dblatex -b.
