[cups] Trying to work around Canon MF743cdw driver bugs on MacOS Catalina

[Brian Demsky]

Different issue.   Below is all the output (on both stdout and stderr).  If I look at the cups logging during normal printing of the same file, it passes a ton of options into the capdftopdl and has a much longer environmental variable setup.

cupsfilter -P /etc/cups/ppd/Canon_MF741C_743C__cb_df_25___25___cb_df_25___2___cb_df_25___2_.ppd -m printer/foo -e oopsla2019-lapor.pdf &> log
