zip files are tagged as text and ISO8859-1

[covener]

Should't they be binary?

[AMES@AQTS ~]$ set|egrep '(ENCODE|BPX)'
_BPXK_AUTOCVT=ON
_BPX_SHAREAS=YES
[AMES@AQTS ~]$  rm -rf x test.zip; mkdir x; touch x/y; zip test.zip x/; ls -lT test.zip
  adding: x/ (stored 0%)
t ISO8859-1   T=on  -rw-------   1 AMES     DEFLT1       170 Jun  4 11:56 test.zip

This breaks legacy unzip/zipinfo:

[AMES@AQTS ~]$ /usr/bin/zipinfo test.zip
[test.zip]
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
zipinfo:  cannot find zipfile directory in one of test.zip or
          test.zip.zip, and cannot find test.zip.ZIP, period.

@HarithaIBM , should we be building off of https://infozip.sourceforge.net/Zip.html#Sources? Looks like LuaDist is 14 years old
