issue with *.sh files in owncloud directory

[patrickjahns]

When the owncloud directory contains any .sh file, the container won't start proplery.

culprit is https://github.com/owncloud-docker/base/blob/master/rootfs/usr/local/bin/entrypoint#L5

entrypoint will be executed in the docker workspace - bash expansion happens
