MiNT 1.10: change blksize on biosfs and pipefs

[Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>]

I don't see any reason why blksize on biosfs cannot be 1024.  This is
so under SunOS and Linux, and it helps utilities like cp and cat which
uses blksize as the size of the buffer.  The same change should be
done for the pipefs.
