Ensure that unwanted tests are correctly excluded when various build
tags are specified, i.e. when the code that they test would be excluded
from compilation.

Note however that the InetDiagMsg struct contains a InetDiagSockID
member, which itself contains some members which are explicitly
specified as big-endian in Linux kernel source:
struct inet_diag_sockid {
__be16 idiag_sport;
__be16 idiag_dport;
__be32 idiag_src[4];
__be32 idiag_dst[4];
__u32 idiag_if;
__u32 idiag_cookie[2];
};
node_exporter currently does not use these members for anything, so this
is acceptable (for now).

* Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.
For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.
@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:
I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.
