fstools: remove bogus warning in the fstab script

/etc/init.d/fstab had some warnings in it to let users know that they
should call "block mount" directly. these ended up in the bootlog.
fix this by splitting the code into boot() and start(). this way the system
will boot without warning but manually starting the script will lead to the
message.

fixes FS#3
