python/semanage: Allow modifying records on "add"

When trying to add a record with a key that already exists, modify
the existing record instead.

Also, fix "semanage -m -e" (add_equal was called instead of
modify_equal), which meant that existing local equivalency couldn't be
modified (though a user could remove it and add a modified
equivalency).

Fixes:

  When a port or login definition present in the policy is modified
  using "semanage port -m", "semanage export" exports the command as
  "port -a" instead of "port -m". This results in "semanage import"
  failing (port already defined). The same is true for port, user,
  login, ibpkey, ibendport, node, interface and fcontext.
