Update dependencies and use the latest PyInstaller version

[kozlovsky]

This PR attempts to fix MacOS segfaulting by upgrading Qt-related dependencies and updating PyInstaller to the latest version.

After the installation on MacOS, it is necessary to open the terminal and perform the following command:

xattr -c /Applications/Tribler.app

Or, alternatively:

xattr -d com.apple.quarantine /Applications/Tribler.app

Without it, MacOS falsely reports that the application is corrupted, but it just means that it is not signed.

As an important consideration, these dependencies should be tested to work on Ubuntu (18.04) with glibc 2.27 as well. That usually places some constraints on PyQt5 and Pillow.

This fact can be a show-stopper for our users:

The only way to properly solve this is to obtain a Developer ID certificate to sign binaries. Until we have this certificate, asking users to execute a command in the terminal looks acceptable to me.

It is not strategically viable to use obsolete versions of PyInstaller and dependencies forever to get a slightly less ugly warning when Tribler first starts.

We currently don't have any ugly warnings on macOS.

We utilize the well-known "right-click" -> "open" trick, which remains the same for all applications from an unidentified developer.

What you're suggesting introduces something "unknown" to Mac users. It's quite suspicious (speaking as a Mac user myself) and not convenient.

I'm not the Product Owner, so I can't stop you from making such a risky change, but @synctext should at least be informed about it.
