Make ‘forbidden tokens, basic’ test more robust.

Browse Source 
While testing the previous patch I noticed that the ‘forbidden tokens,
basic’ test can fail if it runs too fast, because the autom4te cache
files aren’t considered newer than configure.ac.

* tests/tools.at (forbidden tokens, basic): Add delays to ensure
  autom4te.cache files are newer than configure.ac.
