[PATCH v1 12/18] dependencies: pureos-trisquel: Add texlive-plain-generic for the website.

[Denis 'GNUtoo' Carikli]

Without that fix we have the following issue when building a release:

    makeinfo \
         --pdf \
        --no-split \
        -o pages/manual/gnuboot.pdf \
        ../manual/gnuboot.texi

    /usr/bin/texi2dvi: pdfetex exited with bad status, quitting.
    make: *** [Makefile:767: pages/manual/gnuboot.pdf] Error 1

The epsf.tex can be found in the texlive-plain-generic package in
/usr/share/texlive/texmf-dist/tex/generic/epsf/epsf.tex.

This issue was introduced by the commit
08b9e449e94e99c0ec924e2026dc650b63ddc3e5 ("Add a minimal GNU Boot
manual.").
