Fix1: Package upload using Python3 was still broken:
Loading file contents using 'r' does not work in Python 3
and results in an encoding error. Replaced with 'rb'.

Fix2: Be more robust when MIME types are detected:
Treat 'application/x-gzip' as 'application/gzip'.
(This will also allow to use osmclient on OS X)
