[Bug 1921484] [NEW] libedit no longer reads editrc

[Karoly Negyesi]

Public bug reported:

strings /usr/lib/x86_64-linux-gnu/libedit.so.2.0.56 |grep editrc in
Ubuntu 18.04 LTS returns /.editrc as expected but strings
/usr/lib/x86_64-linux-gnu/libedit.so.2.0.63 |grep editrc in Ubuntu 20.04
LTS comes back empty. Verified with strace'ing the mysql client as well:
editrc is no longer picked up, making mysql rather irritating to use.
Peeking at the source code, the problematic commit is d253f567 which
wraps the editrc code in an "#ifdef HAVE_ISSETUGID" which is BSD only. I
am unable to find upstream in version control to help further.
