face+security: Introduce environment variables to set/override transport, pib, and tpm configurations.

- NDN_CLIENT_TRANSPORT: equivalent of transport in client.conf
- NDN_CLIENT_PIB: equivalent of pib in client.conf
- NDN_CLIENT_TPM: equivalent of tpm in client.conf

Whenever an environment variable is set, it takes precedence over any
values specified in the configuration file.
