efl: Use actual destination dirs in warning about using non-standard prefix

Summary:
Instead of relying on ${prefix}/share to be the default for ${datadir} or
${dbusservicedir} use the actual paths where the files will be placed.

Somewhat tricky because of autoconfs desire to keep prefix changeable but
continuously evaluating the variables until they don't change work.
