Drop obsolete Unicode patch

[Gunnar Hjalmarsson]

[Impact]

The Ubuntu 20.04 IBus version includes a patch, which was necessary in 18.04 to make the Ctrl+Shift+u shortcut work, but which has become obsolete later. Currently it prevents users from replacing Ctrl+Shift+u with some other shortcut to avoid conflicts with other applications.

See also:
* Bug #1885749
* https://github.com/ibus/ibus/issues/2163

In the proposed upload that patch has been dropped.

[Test Case]

1. Launch ibus-setup and navigate to the Emoji tab.
2. Change the Unicode code point shortcut to something else.
3. Find that the original shortcut is still effective.
4. Install the ibus packages from focal-proposed.
5. Repeat 1. and 2.
6. Find that the new shortcut works while the original
   shortcut no longer works.

[Regression Potential]

Important to confirm that the default Ctrl+Shift+u shortcut works as intended without the patch. Otherwise the regression risk should be low.

I verified the test case using version 1.5.22-2ubuntu2.1 of the ibus packages from focal-proposed.

Also confirmed that Ctrl+Shift+u works as expected when the unicode-hotkey dconf value is set to default.
