gnu: dblatex: Fix missing texlive binaries and fig2dev.

The binaries for dblatex aren't provided by texlive-updmap.cfg but by
texlive-bin.

* gnu/packages/patches/dblatex-inkscape-1.0.patch: New file.
* gnu/local.mk: Register it.
* gnu/packages/docbook.scm (dblatex)[source]: Use dblatex-inkscape-1.0.patch.
[arguments]<#:tests?>: Enable tests.
<#:phases>: Rename 'set-path to 'wrap-dblatex. Wrap with texlive-bin rather
than texlive-updmap.cfg in PATH and wrap GUIX_TEXMF in 'wrap-dblatex. Add
'check-wrap phase.
[native-inputs]: Add docbook-mathml-1.0.
[inputs]: Restyle. Add texlive-bin. Replace inkscape/stable with inkscape.
Within texlive-updmap.cfg add previously missing: texlive-amsmath,
texlive-auxhook, texlive-bigintcalc, texlive-bin, texlive-bitset,
texlive-bookmark, texlive-colortbl, texlive-courier, texlive-eepic,
texlive-epstopdf-pkg, texlive-eso-pic, texlive-etexcmds, texlive-fancyhdr,
texlive-gettitlestring, texlive-graphics, texlive-graphics-cfg,
texlive-helvetic, texlive-hycolor, texlive-hyperref, texlive-infwarerr,
texlive-intcalc, texlive-kpathsea, texlive-kvdefinekeys, texlive-kvoptions,
texlive-kvsetkeys, texlive-l3backend, texlive-latex, texlive-latex-bin,
texlive-letltxmacro, texlive-ltxcmds, texlive-pdfescape, texlive-pdflscape,
texlive-pdftexcmds, texlive-psnfss, texlive-rerunfilecheck, texlive-symbol,
texlive-times, texlive-tools, texlive-uniquecounter, texlive-url and
