Grant wcnss_filter access to Bluetooth system properties

system/sepolicy change in this topic removes access to
Bluetooth-related system properties from arbitrary SELinux domains.
wcnss_filter daemon needs the access and thus this commit explicitly
grants the access.

Test: Bluetooth pairing and data transfer works
