lmh produces CRLF line terminators

[cmaeder]

Although under linux, my lmh call via docker produces CRLF line endings in my log files, whereas the natively installed version does not:

maeder@lati:/var/data/localmh/MathHub/HelloWorld/smglom$ lmh pdf --force >& log
maeder@lati:/var/data/localmh/MathHub/HelloWorld/smglom$ file log 
log: ASCII text, with CRLF line terminators
maeder@lati:/var/data/localmh/MathHub/HelloWorld/smglom$ /var/data/localmh/bin/lmh pdf --force >& log
maeder@lati:/var/data/localmh/MathHub/HelloWorld/smglom$ file log
log: ASCII text

Apart from the different paths /var/data versus /path/to (see MathHubInfo/Legacy-localmh#235) this is bad for comparisons.
