closes bpo-13497: Fix broken nice configure test. (pythonGH-12041)

Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`. Fixing the test will prevent false positives with pedantic compilers like clang. (cherry picked from commit 90c6fac) Co-authored-by: ngie-eign <[email protected]>
