tools: remote-test-server: Fix UEFI crash return code

- compiletest detects crash as an error code > 127.
- This does not work for UEFI, since UEFI errors are usize by default, and when converting to i32, we just remove the bits in middle. Eg: 0x8000000000000007 becomes 0x80000007
- So in case of crash, we get a negetive value as error  instead of the expected signal when the host is linux.
