Fix for MIT-SHM BadAccess X socket permissions

In some X installations using the MIT shared memory
extension for rendering window elements, Bambu
Studio needs direct access to a UNIX socket
for fast rendering.

This fix passes `--ipc host` with docker run
to allow the container to just have direct access
to the host's IPC system.

The error message that this solves is:

```
(bambu-studio:1): Gdk-ERROR **: 00:02:37.498: The program 'bambu-studio' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
  (Details: serial 316 error_code 10 request_code 130 (MIT-SHM) minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
```
