Correctly implement what was my intent when removing the HAVE_LIBPCAP

stuff - arrange that the interface summary list is set, if we've read a
capture file that has interface information, *regardless* of whether we
have libpcap/WinPcap or not.

That means that summary_fill_in() should fill in the interface
information for the summary if there's interface information from the
capture file, and summary_fill_in_capture() - which is called only if
HAVE_LIBPCAP is defined, and can exist only if HAVE_LIBPCAP is defined
(as it takes an argument of a type that's defined only if HAVE_LIBPCAP
is defined) - just fills in interface information from the capture
options and does so only if there's none from the file.
