syscall: read() should not write anything if reading EOF.
Read() should not write anything when returning 0 (EOF).
This patch does not correct the same bug occuring for :
nbr_read=read(file, buf, nbytes)
When nbr_read<nbytes, nbytes bytes are copied into the virtual
RAM instead of nbr_read. If buf is smaller than nbytes, a
page fault occurs, even if buf is in fact bigger than nbr_read.
