Closed issue by KRSHK on void-packages repository

https://github.com/void-linux/void-packages/issues/11963

Description:
### System

* xuname:  
  *Void 4.19.46_1 x86_64 GenuineIntel uptodate rrFF*

* package:  
  *texlive-bin-2019_1*

### Expected behavior

When compiling with ```xelatex``` a ```.tex``` file using CJKfonts from local ```.fonts``` directory, using ```xecjk``` package, it has to produce a pdf.

### Actual behavior

Since I reboot after important update, the same process give :
```
kpathsea: Running mktextfm rmplus/OT
/opt/texlive/2019/texmf-dist/web2c/mktexnam: Could not map source abbreviation  for OT.
/opt/texlive/2019/texmf-dist/web2c/mktexnam: Need to update ?
mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input OT
This is METAFONT, Version 2.7182818 (TeX Live 2019) (preloaded base=mf)


kpathsea: Running mktexmf OT

l.25 ...infont{rmplus}[Script=CJK, Language=Japanese]
                                                  {rounded-mplus-1p-regular}

```

### Steps to reproduce the behavior
You need ```xetex``` and ```xecjk``` installed, and use the minimal example below:
```
\documentclass[9pt]{article}
\usepackage{%
     fontspec,%
     xeCJK%
 }

\setmainfont{Latin Modern Mono} %your favorite font
\setCJKmainfont{rmplus}[Script=CJK, Language=Japanese]{rounded-mplus-1p-regular}
 %your favorite CJK font, hre rounded M+ 1p regular

\begin{document}
test
{\CJKfamily{rmplus} テスト}
\end{document}
```

### More
I discovered it after trying to use upTex. I had to install new packages with ```tlmgr``` and reboot.
I tought I made some mess with mapping and everything else, so I reinstalled from scratch voidlinux. The result is the same.
