texmfcnf.lua is broken for ConTeXt.

[amano.kenji]

After reading /usr/share/texmf-dist/web2c/texmf.cnf, I concluded that texmfcnf.lua should set TEXMFSYSVAR="selfautoparent:/var/lib/texmf", TEXMFSYSCONFIG="selfautoparent:/etc/texmf", TEXMFDIST="selfautodir:share/texmf-dist".

If people who use TexLive installer has no problem with texmf.cnf using the above values for TEXMFSYSVAR, TEXMFSYSCONFIG, and TEXMFDIST, then they wouldn't have a problem with texmfcnf.lua having those same values, either.

Arch Linux texlive-core's texmfcnf.lua sets TEXMFOS="selfautodir:share", but I don't know whether TEXMFOS="selfautodir:share" is necessary.
