tests: add Novell DOS tool baseline suite

Add DOS-side baseline scripts for the Novell tools used to compare the
reimplemented public utilities.

The suite covers the current baseline set:

  MAP
  SLIST
  WHOAMI
  LOGIN / LOGOUT
  NDIR
  NCOPY
  FLAG
  FLAGDIR
  CREATOR
  RIGHTS
  GRANT
  REVOKE
  REMOVE

It also includes supporting trustee, rights, rename, move, delete and
file-operation tests.

Each test writes reproducible output into a per-tool CMP directory and
provides a matching ZIP helper for collecting the results. The ZIP
helpers clean generated test trees afterwards so SYS: does not keep
accumulating temporary directories.

This is the Novell baseline layer only. A later change can extend the
same scripts to run the full comparison cycle:

  NPUBLIC baseline -> PUBLIC implementation -> NPUBLIC control

+# Test flow:
+#
+# 1. `FILPREN.BAT`
+#    - creates F:\TFILE
+#    - writes baseline output files to F:\TFILE\PRE\*.OUT
+#
+# 2. manual `NPUBLIC\FILER`
+#    - inspect/change files in F:\TFILE
+#
+# 3. `FILPOSTN.BAT`
+#    - writes post-FILER output files to F:\TFILE\POST\*.OUT
+#    - compares PRE vs POST with FC
+#
+# 4. optional `FILCMPN.BAT`
+#    - repeats only the comparisons
+#
+# 
+MANUAL FILER CHANGE SET:
+  Recommended controlled changes:
+    A.TXT       toggle Hidden
+    B.TXT       toggle Read Only
+    KEEP.TXT    toggle Archive Needed
+
+  For a readback-only pass, inspect the same entries but do not save changes.
+  FILPOSTN.BAT should then show no FC differences.
+
+
+Expected:
+# - FC reports no differences if FILER was only inspected.
+# - FC reports intentional differences if attributes/metadata were changed.
