So, just to be clear here about the tradeoffs of the two solutions
"fix the packaging tooling" or "make it dynamic in wine":

On Debian/Ubuntu, libpcap0.8-dev will need to be added to package
build dependencies or a user will never be able to turn this feature
on.  This will cause Wine to statically link a dll, and for debhelper
to then detect that static link, figure out it comes from the
libpcap0.8 package, and add that dependency to the {$shlibs:Depends}
substitution variable.  This requires modifying the package rules file
to override dh_shlibdeps to either 1) exclude calculating the
particular DLL in question, or 2) manually remove libpcap0.8
afterwards.

Both those are fairly straightforward in deb-land.  But, so is
applying Andre's patch to a distro package.  I don't know about
tooling for other distros.
