ss: change aafilter port from int to long (inode support)

The aafilter struct considers the port as (usually) 32 bit signed
integer. In case of a unix socket, the port is used with an inode
number which is an unsigned int. In this case, the 'ss' command
fails because it assumes that the value does not look like a port
(<0).

Here an example of command call where the inode is passed and
is larger than a signed integer:

ss -H -A unix_stream src :2259952798
