Take into account ignore suffixes from the server configuration

Steps to reproduce:

1. configure nuxeo-drive-config.json to customize the ignored suffixes

    "ignored_suffixes": [".crdownload", ".lock", ".nxpart", ".part", ".partial", ".swp", ".tmp", "~"], 

2. start Nuxeo server
3. create a workspace and synchronize it with Drive
4. upload to the workspace 4 files whose names are foo.tmp, foo.part, foo.bak and foo.txt
5. set up your local Drive client
6. enable local synchronization
7. wait for the synchro to complete
8. observe that a folder has been created with only 1 file in it : foo.tmp => foo.bak has been banned where the "bak" suffix is allowed now

Look at the debug.logfile to see the configuration and the banned items

Expected behavior: foo.tmp and foo.bak are synchronized to respect the global configuration
