[Linux] Crash on GetGameControllerMapping when plugging in the Magic-NS wireless controller adapter in XInput mode



Reproduction steps:
1. Open a new or an existing project
2. Go to Edit > Project Settings... > Player
3. Change the Active Input Handling to Input System Package (New)
4. Plug in the Magic-NS wireless controller adapter in XInput mode

First 5 lines of the stack trace:
#0 0x00563cc9b0ddec in burst_signal_handler(int, siginfo_t*, void*)
#1 0x007f2227140980 in funlockfile
#2 0x007f2226ecb4e1 in __nss_passwd_lookup
#3 0x00563cc9ff1361 in GetGameControllerMapping(void*)
#4 0x00563cc9fe907e in SDLGamepadDeviceDescriptor::SDLGamepadDeviceDescriptor(int)

Reproducible with: 2021.1.0a1, 2021.1.17f1, 2021.2.0b7, 2022.1.0a5
Not reproducible with: 2019.4.29f1, 2020.3.16f1

- Not reproducible on Windows
- Could not test on macOS due to the Magic-NS adapter not working on that OS
- From a separate report, it seems that the crash also occurs on Ubuntu 21.04 (and Arch Linux) by plugging in a regular Xbox controller
