[Hub] [Linux] Cannot run Hub as Glibc 3.4.20-21 is required but unavailable in CentOS 7

As of Hub 1.3.3, the Linux native implementation requires Glibc 3.4.20/3.4.21. As these versions of Glibc are currently unavailable in CentOS 7, the hub cannot be run, reporting the following errors to log:

{"level":"error","message":"Unhandled promise rejection, reason: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /tmp/.org.chromium.Chromium.IGPlEb)\n\tstack Error: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /tmp/.org.chromium.Chromium.IGPlEb)\n at process.module.(anonymous function) [as dlopen] (ELECTRON_ASAR.js:172:20)\n at Object.Module._extensions..node (module.js:598:18)\n at Object.module.(anonymous function) [as .node] (ELECTRON_ASAR.js:186:18)\n at Module.load (module.js:503:32)\n at tryModuleLoad (module.js:466:12)\n at Function.Module._load (module.js:458:3)\n at Module.require (module.js:513:17)\n at require (internal/module.js:11:18)\n at Object.<anonymous> (/tmp/.mount_UnityHE6XpQi/resources/app.asar/node_modules/@unityhub/unity-editor-license/license.js:1:170)\n at Object.<anonymous> (/tmp/.mount_UnityHE6XpQi/resources/app.asar/node_modules/@unityhub/unity-editor-license/license.js:29:3)","timestamp":"2019-10-24T14:54:28.315Z"}

Steps to reproduce:
1) On a machine running CentOS 7, install or upgrade the latest Unity Hub (1.3.3+)
2) Observe the Hub will fail to launch and note the Glibc errors reported to the log at /home/teddy.kardos/.config/UnityHub/logs/
