tests: always update generated tests silently

[Ralf Wildenhues]

Reading the log files, I notice that I forgot to use
--enable-silent-rules throughout, so that all the test generation is
done verbosely and a bit annoying when reading the log files.  Now, even
if I won't forget again, our users likely will.  Would you mind just
generating them completely silently by default?

Alternatively, we could prefix them with
        @$(AM_V_GEN)
        @$(AM_V_at)
        ...

then in silent-rules mode the GEN line would still be output.

Or should we go the next step and use AM_SILENT_RULES([yes])?

What do you think?

Thanks,
Ralf
