brew tap fails with invalid formula due to disabled bottle :unneeded about homebrew-qt4

[cartr]

Thank you for reporting this issue! I don't currently have access to a Mac to test changes to this tap. Is there any chance you could submit a Pull Request with the needed changes?

Sadly, I don't use macOS except in the sense that a project I work on has macOS CI which someone else set up. So I cannot test it either. :(

(I can do a lot of investigative work and digging to find the cause of the problem, but that's about my limit. I'm not even sure I fully understand what this formula statement does.)

Based on following links from that ticket and Homebrew/brew#12913 to other projects encountering the same issue and seeing how they resolved it, simply removing those lines may be the right solution.

Alright, I tried to test this out by removing those lines and pointing the Meson CI at my fork, results are here: https://github.com/eli-schwartz/meson/runs/5513240977?check_suite_focus=true

The error is gone, qt4 is successfully installed and the CI that tries to build a program against Qt4 now passes.

My hope is that that means my fix is correct. :D
