Merge branch 'rs/archive-zip-many' into maint

"git archive" did not use zip64 extension when creating an archive
with more than 64k entries, which nobody should need, right ;-)?

* rs/archive-zip-many:
  archive-zip: support more than 65535 entries
  archive-zip: use a local variable to store the creator version
  t5004: test ZIP archives with many entries
