Auto merge of #25248 - MeFisto94:fix-linux-crash-libbacktrack, r=jdm

Workaround for #24984 - Solve crashes when panicking / Hang Monitoring by using cargo's patch mechanism to work around a bug in libbacktrace

Temporarly patch backtrace-rs

---
libbacktrace contains an error leading to invalid pointers when trying to backtrace a stacktrace.
These invalid pointers led to a crash, whenever a panic or Hang Monitoring happened (which is where the stack is captured).
Since fixing the issue properly at gcc will require some time, I've created a small and patched version of backtrace-rs, which will be used as patch here.

- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix #24984
- [X] These changes do not require tests because they fix a native crash which is a) really obvious and b) shouldn't be a regular case.
