Fix PS test crash

Browse source 
When the tests run ghostscipt on ps2 files it crashes with:

  GPL Ghostscript 9.53.3: Unrecoverable error, exit code 1

The problem is the "-c 2 .setlanguagelevel -f" on the gs command line
to set ghostscript to language level 2. I'm not sure why this no longer works.

.setlanguagelevel is not mentioned any where in the gs custom operators listed in
https://www.ghostscript.com/doc/current/Language.htm

I assume this operator was meant for ghostscript internal use and
is no longer exposed in recent versions. Remove it from the test.
