Add sepolicy rules to grant wificond permission to use SIOCSIFHWADDR ioctl. This permission is needed to dynamically change MAC address of the device when connecting to wifi networks. Bug: 63905794 Test: Verified manually that wificond can dynamically change MAC address. Change-Id: If2c6b955b0b792f706d8438e8e2e018c0b4cfc31
