gnu: texlive-libkpathsea: Better default values in "texmf.cnf".

Browse source 
* gnu/packages/tex.scm (texlive-libkpathsea)[arguments]<#:phases>: Use better
default values in "texmf.cnf".  This fixes slowness in ".tex" documents
compilation, left-over "{/" directories in compilation directory, and helps
LuaTeX finding system fonts.
