macos: Make tray installation optional

Now that we have 2 different packages for the tray and crc, we can make
the tray installation optional.

The tray is not installed by default. This matches the Windows
installer.

One corner case is:
1. Install crc with the tray
2. Upgrade to a new crc version but don't install the tray
-> the tray remains installed
