VTS: fix VtsHalKeymasterV3_0Target issue

Failed cases:
AttestationTest.RsaAttestation
AttestationTest.EcAttestation

Analysis:
The verify_attestation_record() in Keymaster_hidl_hal_test.cpp calls
parse_attestation_record() to set the value of att_challenge. It fails
to compare att_challenge with challenge by memcmp.
Because setToExternal() method uses buffer pointer to local variable
(record), not use memcpy to copy into itself buffer in
parse_attestation_record(). When it leaves the parse_attestation_record(),
we will get the att_challenge which is null buffer to compare with challenge
incorrectly.

Fix: use memcpy to copy the buffer.
