Remove EXPERIMENTAL = True from all non-BVT tests.

The EXPERIMENTAL setting is being deprecated; the setting is a no-op
when the test isn't in the BVT and isn't in a suite with `file_bugs`
set to True.  This removes the EXPERIMENTAL setting from control
files where the setting has no effect.

BUG=None
TEST=None
