thinking about this a bit more, this seems doable, albeit only for POSIX
mode. For non-POSIX mode we could potentially break WIndows application
that open only with FILE_APPEND_DATA: I checked with a torture test that
Windows doesn't enforce append behaviour for FILE_APPEND_DATA|SYNCHRONIZE.
For POSIX opens we should also allow combinations like
FILE_READ_ATTRIBUTES|FILE_APPEND_DATA to map to O_APPEND, so clients can
write in append mode to the handle and still are able to fstat() it.

oh, forgot to mention that this fixes the failing copy_chunk copy from
the Linux kernel client in posix mode.
