Andrew Zaborowski cb6289b622 auto-t: Work around wpa_s config issue in testP2P
Since commit 922fa099721903b106a7bc1ccd1ffe8c4a7bce69 in hostap, our
setting of config_methods on P2P-client interface was ignored.  Work
around that commit, in addition to the previous workaround we have in
this test, to again ensure the correct config_methods value is used.
