This was working before, but only if realloc a) succeeded and b) did not
move the buffer to a different location. ''**buf = **new_buf' then
writes the value of *new_buf's first field into that of *buf.

There is no special reason to use the secure version of getenv, thus let's
simply use getenv().

After commit 8250bc9f ("ss: Unify inet sockets output") raw sockets
are displayed as udp because dgram_show_line() is used for both and
thus IPPROTO_UDP is used for both so proto_name() returns "udp".
Fix this by checking dg_proto which is set according to the caller of
dgram_show_line().
