  [sanitizer_common] Fix TgKill on Solaris (#98000)

While working on safestack on Solaris, I noticed that the `TgKill`
implementation is wrong here: `TgKill` is supposed to return `-1` on
error, while `thr_kill` returns `errno` instead. This patch compensates
for that.

This went unnoticed so far since `TgKill` has been unused.

Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11` together
with a subsequent patch to make safestack actually work on Solaris.
