LOG: Fix rtsan build with musl (#119674)

fd_set is defined by `sys/select.h`. On musl, this header is not
transitively included by the other headers.

Failure message:
```
compiler-rt/lib/rtsan/rtsan_interceptors_posix.cpp:761:37: error: unknown type name 'fd_set'; did you mean 'fd_t'?
  761 | INTERCEPTOR(int, pselect, int nfds, fd_set *readfds, fd_set *writefds,
      |                                     ^~~~~~
      |                                     fd_t
