[clang-tidy] Fix bugprone-bad-signal-to-kill-thread crash when `SIGTERM` is not a literal.
If `SIGTERM` is not a literal (e.g. `#define SIGTERM ((unsigned)15)`) bugprone-bad-signal-to-kill-thread check crashes.

[clang-tidy] Fix bugprone-bad-signal-to-kill-thread crash when `SIGTERM` was undefined after definition.
`PP->getMacroInfo()` returns nullptr for undefined macro, which leads to null-dereference at `MI->tockens().back()`.
