fs: add RWF_APPEND
This is the per-I/O equivalent of O_APPEND to support atomic append
operations on any open file.
If a file is opened with O_APPEND, pwrite() ignores the offset and
always appends data to the end of the file. RWF_APPEND enables atomic
append and pwrite() with offset on a single file descriptor.
