util.startup: Ensure prosody.paths are absolute (see #1430)
Normally these paths are injected into the installed 'prosody'
executable as absolute paths, but it is possible to override at least
the config path via environment variable or command line argument. This
makes sure a path relative to pwd stays relative to that instead of the
data directory.
