[sanitizer_common] Adjust signal_send.cpp for Linux/sparc64 (#100538)

```
  SanitizerCommon-ubsan-sparc-Linux :: Linux/signal_send.cpp
```
currently `FAIL`s on Linux/sparc64 (32 and 64-bit). Instead of the
expected values for `SIGUSR1` (`10`) and `SIGUSR1` (`12`), that target
uses `30` and `31`.

On Linux/x86_64, the signals get their values from
`x86_64-linux-gnu/bits/signum-generic.h`, to be overridden in
`x86_64-linux-gnu/bits/signum.h`. On Linux/sparc64 OTOH, the definitions
are from `sparc64-linux-gnu/bits/signum-arch.h` and remain that way.
There's no `signum.h` at all.

The patch allows for both values.

Tested on `sparc64-unknown-linux-gnu` and `x86_64-pc-linux-gnu`.
