Remove a few unsuitable scripts from the "veryquick" test suite. Also have every second testrunner.tcl process favour running test scripts that contain text like "testrunner: slow" before any others.

#
# NOTE: It is known that the win32lock-2.2-* tests may fail if the system is
#       experiencing heavy load (i.e. they are very timing sensitive).  This is
#       primarily due to the AV retry delay being set to 1 millisecond in the
#       win32lock-2.1 test (above).  While it is important to test this corner
#       case for the AV retry logic, a failure of this test should probably not
#       be interpreted as a bug in SQLite or these test cases.
