[dts] [PATCH] tests/TestSuite_multiple_pthread.py: Updated test_positive() and teardown() functions.

[<usurekha@marvell.com>]

From: usurekha <usurekha@marvell.com>

Added script to get the available max cpu depends on DUT config.
Did modifications in teardown() to close the tester scapy sessions properly.
