This commit fixes fd_fdstat_set_flags resetting the fd offset due to it reopening the file every time. This fix gets the current offset before reopening and restore the offset with seek. This addresses #1865.

NB: A couple of existing tests are actually spec'd wrong. To fix, I introduced addition Seek calls before checking removing append flag.

Maybe too late for a nit, but please constants for the whence: io.SeekStart, etc…
