audit: add saddr_fam filter field
Provide a method to filter out sockaddr and bind calls by network
address family.
Existing SOCKADDR records are listed for any network activity.
Implement the AUDIT_SADDR_FAM field selector to be able to classify or
limit records to specific network address families, such as AF_INET or
AF_INET6.
An example of a network record that is unlikely to be useful and flood
the logs:
type=SOCKADDR msg=audit(07/27/2017 12:18:27.019:845) : saddr={ fam=local
path=/var/run/nscd/socket }
type=SYSCALL msg=audit(07/27/2017 12:18:27.019:845) : arch=x86_64
syscall=connect success=no exit=ENOENT(No such file or directory) a0=0x3
