utils: make API key generator more random

The API key generator abused temporary filenames in what seems to be an attempt
of creating keys that unambiguously specified the user and thus were unique
across users. A final hashing did however remove that property.

More importantly, tempfile is not documented to use secure random numbers ...
and it only uses 6 characters, giving approximately 36 bits of entropy.

Instead, use the cryptographically secure os.urandom directly to generate keys
with the same length but with the full 160 bits of entropy.

Reported and fixed by Andrew Bartlett.
