No longer limit the length of runtime of 3 Chrome Endure tests.
No longer limit the length of runtime of 3 Chrome Endure tests.

Previously, 3 Chrome Endure tests would fail with buffer overrun errors
after several hours of runtime.  The problem was avoided by reducing the
runtime of the tests until the problem could be fixed.  Recent fixes to
pyauto's remote inspector module are likely to have fixed the problem,
so we no longer limit the runtime of the 3 Chrome Endure tests in question.

BUG=chromium-os:32357
TEST=Verified that the Gmail compose/discard test can run for the full 6
hours, even though it previously used to fail consistently after about
5 hours with a buffer overrun error.
NOTRY=true
