dbus-send: check usage a bit strictly

This commit does several more strictly check for dbus-send as its usage
suggested.

* now --address is an invalid option but --address=, this just like the
  others, say --reply-timeout=, --dest=, --type=
* --print-reply= only take an optional argument "=literal"
* --print-reply= will cause error with missing MSEC and invalid MSEC
  will cause invalid value error
* --dest= will cause error with missing a NAME and also call
  dbus_validate_bus_name to verify the NAME
