[Linux][Vulkan] Crash on "__sigaction" when Vulkan is set as default Graphics API



Reproduction steps:
1. Create and open a new Project
2. Go to Edit > Project Settings > Player window
3. Under “Other Settings” uncheck “Auto Graphics API for Linux”
4. Set the “Vulkan” option at the top of the list
5. Restart the editor

Expected result: The Editor opens up using Vulkan API
Actual result: The Editor crashes

Reproducible with: 2022.2.3f1, 2022.2.11f1, 2023.1.0b8, 2023.2.0a6
Not reproducible with: 2020.3.46f1, 2021.3.21f1, 2022.2.2f1

Reproducible on: Ubuntu 22.04 (AMD GPU)
Not reproducible on: Ubuntu 20.04 (AMD GPU), Ubuntu 22.04 (Nvidia GPU), Windows 10

First lines of the stack trace:
0x007fed40fca520 in __sigaction
0x0055df7ab2ed17 in Performance::TrackerManager::StartWatch(unsigned long)
0x0055df7a5df6da in Ticker::TickProfileInternal(bool)
0x0055df7a6ca1cc in Application::TickTimer()
0x0055df7ac5dcce in MainMessageIteration(void*)

- Personally I was not able to get stack trace, but the crash did occur
- The issue was reproducible after a clean install of Ubuntu 22.04
- When official AMD GPU drivers are installed, Editor does not open on 2022.2 versions. These are the last lines of Editor.log:

: CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options{noformat}
