  getlogin tests: Avoid #ifdefs when sharing code between modules.
  
  * modules/getlogin_r-tests (Files): Add tests/test-getlogin.h.
  * modules/getlogin-tests (Files): Likewise. Remove
  tests/test-getlogin_r.c.
  * tests/test-getlogin.h: Extracted from tests/test-getlogin_r.c.
  * tests/test-getlogin.c: Extracted from tests/test-getlogin_r.c.
  * tests/test-getlogin_r.c: Include test-getlogin.h. Omit code that tests
  getlogin().
