libbpf-tools: Fix bindsnoop types usage

Similarly to tcpconnect [1] and tcpconnlat [2], bindsnoop is also making use of the __int128 type and that is not defined for 32-bit platforms. Replace __int128 with a portable array of __u8 and adjust the usage sites as needed. [1] iovisor@f270073 [2] iovisor@9931ea3 Signed-off-by: Jesus Sanchez-Palencia <[email protected]>
