Merge dtksh patches from one of the CDE developers (#85)

Browse source 
This merges some fixes to support building dtksh with -DBUILD_DTKSH.
These patches were sent through private email from the CDE developer
Chase. The reason these patches were submitted is because Chase wishes
to include ksh in CDE as an up-to-date git submodule. Quote from Chase:
"... my priority is to get your new version into our code as a git
 submodule, and do it quickly before our code bases differ too widely."

Link to CDE project for anyone interested:
https://sourceforge.net/projects/cdesktopenv/

Although the patches were privately discussed, there are some public
emails on the CDE mailing list (links shortened due to long URLs):
ksh-chaos thread:   https://bit.ly/3hjJ83b
dtksh alias thread: https://bit.ly/3hkzKfJ

The main fix is for suid_exec, which is now told that /usr/dt is a
valid directory to run from via preprocessor flags. A patch for
Shift-JIS was also submitted, but it isn't in this commit because it
isn't an effective fix for the existing Shift-JIS bugs. I will be
giving that patch some more testing.
