Ryan Prichard b4722cc4c9 [libc++][test] Fix infinite loop when mkstemp fails
mkstemp is guaranteed to make at least TMP_MAX attempts to create the
random file, and if it can't, it fails with EEXIST. get_temp_file_name
shouldn't call mkstemp again if it fails with anything other than
EEXIST. A single mkstemp call seems sufficient.

On Android, I've seen mkstemp fail with:
 - EROFS (because cwd wasn't set to a writable filesystem)
 - EACCES (because cwd pointed to a dir owned by root, but the test
   program was running as the shell user instead)

Previously, get_temp_file_name would run forever in these situations.

See D4962 and "llvm-svn: 229035"
