Add a separate cookie for the start of a PPAPI test to help reduce test
flakyness.

This also ups the timeout time for actually running the test. We don't know
what the tests do (some of the file ones do a lot of I/O), so the short timeout
is somewhat dangerous. We have not historically had many problems with hanging
tests other than problems with startup (which has a shorter timeout), so I
think the longer test timeout is unlikely to cause problems.

Uhm, this is all commented out?
