Log Message:
Make sure reads on empty files reach PUFFS filesystems

Sending a read through the page cache will get the operation
short-circuited. This is a problem with some filesystems that
expect to receive the read operation in order to update atime.

We fix that by bypassing the page cache when reading a file
wich a size known to be zero.
