matrix-synapse: Allow keys to be generated
The matrix-synapse user has `createHome = true;` which runs before the
`preStart` script, so the home directory will always exist and the block
will never execute.

Also don't include default path to keys in the configuration file,
because synapse will choke if it tries to open them before they
exist (even with `--generate-keys`).
