[compiler-rt] [Sanitizer] Call Die() instead of Abort() when failed to reserve shadow memory range (PR #107833)

[via llvm-commits]

https://github.com/Enna1 created https://github.com/llvm/llvm-project/pull/107833

I grep the code and find that `Abort()` is only called in `Die()` when the flag `abort_on_error` is set.
Thus, if reserving shadow memory range fails, `Die()` rather than `Abort()` should be called. In this case, the flag `abort_on_error` will be respected and the die callbacks will be called.
