Fix hostname when get_distribution_version() returns a string.

The distro version is a string ('jessie/sid') on Debian unstable and testing.
Because load_platform_subclass() evaluations every subclass as it loops,
comparing numbers when get_distribution_version() does not return a number will
break.

This patch fixes that by returning a number (`0`) when we have an invalid
version, instead of returning `None` or a string.
Support for OS X 10.10 DP3.
Needs additional divisor.

Bugfix: bulletproof unexpected_error_msg at gce.py

This method was still failing for me with a "missing http_code" message. After applying this change, the error message is:

```
msg: Unexpected response: {'value': 'PyCrypto library required for Service Account Authentication.'}
```

I wanted to contribute a rock-solid `unexpected_error_msg` implementation.

Fix extra newline at end of hostname for Fedora

This fixes a bug introduced by 138b45e3.
The hostname has an additional newline at the end which leads to the
state always being 'changed: true' even if the hostname is unchanged.
