11.1 is an official update for macOS Big Sur. We should maybe add a custom macOS version parser which falls back if minor version changes so we don't have to maintain all the versions manually.
Fixes#4722
New webkit build, generated by 19f21b1bdee3e26aa22b344f1275ee3acf80749a, changed webkit build
layout: now there are subfolders that contain libraries and executables, and some of the dependencies are no longer bundled.
This patch:
- teaches launch doctor new directories structure: subfolders are now inspected for missing dependencies, and they are also used in the `LD_LIBRARY_PATH`.
- adds `libevent` and `libicudata` libs to the mapping for ubuntu 18.04
