With --with-libpcap=included the bug is gone.  Is it a bug in Ubuntu's
version of libpcap or in the nmap's way of libpcap's usage?

I think it is neither; rather it is that Valgrind doesn't know the way
setsockopt is used in this case. Nmap's version of libpcap might have
been patched to make the warning go away.

Oh, this is a known issue.  I should have googled first, sorry for the
noise.
