[PATCH] t5608: avoid say and use skip_all for consistency

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

Printing a message directly to stdout could affect TAP processing
and is not really needed, as there is a standard way to skip all
tests that could be used instead (including a message).

While at it, update the message to better reflect the use of
booleans and get rid of the prerequisite.
