crypto/x509: save the temp dir in TestReadUniqueDirectoryEntries

In CL 231958, TempDir was changed to create a new temp directory on
each allocation, on the theory that it is easy to save in a variable
for callers that want the same directory repeatedly. Apply that
transformation here.

Updates #38850
