localrepo: remove unneeded os.unlink call in wwrite

The opener already unlinks the filename before 'w'riting, for both
the symlink and the normal file case. It also now resets the flags
for normal files on 'w'rite, which makes this os.unlink call completely
redundant.

For Windows, removing this extra unlink call helps to avoid tripping
issue2524 (os.unlink followed by a write).

  $ hg branch B
  marked working directory as branch B

b is now branch head of B, and a topological head
a is now branch head of A, but not a topological head

  $ cd ..
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo a2 >a2
  $ hg ci -Ama2
  adding a2

a2 is now the new branch head of A, and a new topological head
it replaces a former inner branch head, so it should at most warn about
A, not B
