0c6054fc9f depends: Bump QT to LTS release 5.9.8 (THETCR)
Pull request description:
This update is only a minor version but in contrary to 5.9.7 it's a LTS release.
It doesn't add any new functionality to Qt but fixes multiple security issues and bugs.
Including some race conditions and annoying bugs on macOS.

ACK 0c6054fc9f. Lightly tested on macOS 10.14.6. Not really sure what difference would matter on macOS.
