The BSS id numbers were assumed to start from 0 at the beginning of this
test case, but that is only the case if this is run as the first test
after starting wpa_supplicant. Fix the test case to figure out the id
values dynamically to avoid false errors.

Only run-tests.py is actually executed, so there is no need to specify
the interpreter in all the helper files and test script files.
