tahoefuse: fix typo which could cause data corruption

a typo in the 'flags2mode' code would wind up passing the O_APPEND
flag into the os open() call, which would cause the file to be opened
in 'strict append' mode, i.e. all writes extend the file, regardless of
calls to seek.

this causes a problem for tahoefuse in that the seek() calls made to
filehandles open through fuse would be ignored when write()s occurred.
this was evidenced by corruption seen when using rsync.  it turns out
that rsync actually makes overlapping writes in some cases, i.e. even
when writing a new fresh file out, it still doesn't write a simple
contiguous span of data, but will make writes overlapping data already
written. this is probably related to the way it manages data blocks
internally for rolling checksums etc.  at any rate, this bug would
thus cause rsync in those cases to write a chunk of duplicate data
into the file - leading to tahoe securely and reliably storing the
wrong data.

fixing this, so that non-append file opens do not pass O_APPEND seems
to eliminate this problem.

tahoefuse: return bogus but useful data to statfs call

previously tahoefuse returned the fs stat for the filesystem the fuse plugin

tahoe than the local machine has free disk space, at which point Finder will
refuse to copy 'too much' data.

this changes it so that tahoe always reports 2TiB used of an 8TiB filesystem
this is entirely bogus, but allows copies of up to 2TiB to be initiated.
