Improve installation for MacOS to avoid issues with switching to lacinka layout in many applications

[kakareko]

Hi, I suggest changing the installation procedure of the keyboard layout for MacOS.

Looks like putting a custom keyboard layout in "~/Library/Keyboard Layouts" directory leads to issues with switching to this layout in many different applications.

The issue is resolved by putting the layout bundle in "/Library/Keyboard Layouts" directory.

There may be a better solution to the issue. However, this workaround worked for me and is recommended on Stackexchange and on Apple Discussions.
