Subject: [PATCH] Gracefully fail FAPI init when it's not compiled in

Instead of emitting:

   WARNING: Getting tokens from fapi backend failed.

errors when FAPI support is not compiled in gracefully fail the FAPI

init and don't log any warnings. We'll still produce a message

indicating this is what's happened in verbose mode, but normal operation

no longer gets an unnecessary message.

Fixes #792
