dialyzer: Fix a bug concerning the option 'plt_remove'
[James Fish:] Dialyzer always asserts that files and directories passed in its options exist. Therefore it is not possible to remove a beam/module from a PLT when the beam file no longer exists. Dialyzer should not to check files exist on disk when removing from the PLT.
