archive-zip: support UTF-8 paths
Set general purpose flag 11 if we encounter a path that contains
non-ASCII characters. We assume that all paths are given as UTF-8; no
conversion is done.
The flag seems to be ignored by unzip unless we also mark the archive
entry as coming from a Unix system. This is done by setting the field
creator_version ("version made by" in the standard[1]) to 0x03NN.
The NN part represents the version of the standard supported by us, and
this patch sets it to 3f (for version 6.3) for Unix paths. We keep
creator_version set to 0 (FAT filesystem, standard version 0) in the
non-special cases, as before.
But when we declare a file to have a Unix path, then we have to set the
file mode as well, or unzip will extract the files with the permission
set 0000, i.e. inaccessible by all.
