patch fuse so it forces DIRECT_IO for WRONLY opens

This patch forces fuse to use DIRECT_IO for files opened
WRONLY, so it won't try and read a block in before writing
a partial block.

This fix may be preferable to the other patch, since it shouldn't
make a WRONLY open fail because read/write isn't allowed.

To put this in -head, fuse also needs to be patched to invalidate
buffers when DIRECT_IO is enabled, because otherwise reads may
get stale cached data.
