[bug] The --uid parameter doesn't work.

[robvinson]

Describe the bug The --uid flag introduced by https://github.com/sensepost/objection/pull/526 does not work. Maybe providing a process ID (--pid) flag could be an alternative?

Expected behavior Attach to the application running under the UID indicated by the --uid flag.

Evidence / Logs / Screenshots Running a command like: objection --uid 12 --name com.some.package start errors out with a stacktrace like the below. It appears that attach() doesn't actually support a UID parameter.

  File "/home/me/objection/utils/agent.py", line 250, in attach
    self.session = self.device.attach(self.pid, uid=self.config.uid)
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/me/venv/lib/python3.11/site-packages/frida/core.py", line 86, in wrapper
    return f(*args, **kwargs)
           ^^^^^^^^^^^^^^^^^^
TypeError: Device.attach() got an unexpected keyword argument 'uid'

Environment (please complete the following information):

• Frida Version: 16.4.8
• Objection Version: master d9c989d

Thanks, I do not currently have an environment where I can test this, but do you mind checking if https://github.com/frida/frida/issues/1353#issuecomment-990424623 works within your environment in order to narrow down where the issue might be.
