LOG: [OpenMP] Use pthread_self for __kmp_gettid on Solaris (#138510)

Building `openmp` on Solaris/amd64, I get

```
In file included from openmp/runtime/src/kmp_utility.cpp:16:
openmp/runtime/src/kmp_wrapper_getpid.h:47:2: warning: No gettid found, use getpid instead [-W#warnings]
   47 | #warning No gettid found, use getpid instead
      |  ^

```

There's no reason to do this: Solaris can use `pthread_self` just as AIX
does.

Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.
