Use Dropbox's repo to install on Debian-family distributions (#1)

* Remove trailing whitespace

* Use ansible_os_family for Debian/Ubuntu detection

Use ansible_os_family == "Debian" instead of testing
ansible_distribution against "Debian" and "Ubuntu".

* Use Dropbox's repo to install on Debian-family distributions

Dropbox provides an apt repository for Debian and Ubuntu.  Use it to
install dropbox instead.  Fall back to curl pipeline install for
everything else.

Name the control script 'dropbox' on non-apt installs to match the name
of the script installed through apt.
