[compiler-rt] [NFC][UBSAN] Fix minimal UBSAN test names (PR #137244)

[Vitaly Buka via llvm-commits]

https://github.com/vitalybuka created https://github.com/llvm/llvm-project/pull/137244

Same approach as in Asan.

Now it's going to print:
```
Failed Tests (2):
  UBSan-Minimal-i386-linux :: TestCases/icall.c
  UBSan-Minimal-x86_64-linux :: TestCases/icall.c
```

Before it was:
```
Failed Tests (2):
  UBSan-Minimal-x86_64 :: TestCases/icall.c
  UBSan-Minimal-x86_64 :: TestCases/icall.c
```
