bookmarks: directly use base dict 'setitem'

The bmstore '__setitem__' method is setting an extra flag that is not needed
during initialization. Skipping the method will allow further cleanup and yield
some speedup as a side effect.

  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
