ZIP permissions

[mojodna]

When unzipping an archive with unzip (e.g. s3://vector-tiles-prod/20180326/a8a6c/all/11/333/744.zip), files have 0000 permissions and need to be manually chmod'd by root to become readable.

The fix appears to be to add

info.external_attr = 0755 << 16L

after

tilequeue/tilequeue/metatile.py

Line 54 in 4062c1a

info = zipfile.ZipInfo(tile_name, date_time)

Ditto for

tilequeue/tilequeue/rawr.py

Line 537 in 44b1aa6

zip_info = zipfile.ZipInfo(fmt_data.name, date_time)
