[libvirt] [PATCH] dnsmasqReload: avoid mingw link failure

[Eric Blake]

* src/util/dnsmasq.c (dnsmasqReload): Mingw lacks kill, but is not
running a dnsmasq daemon either.
---

I'm not as familiar with the mingw cross-build setup, but I finally
got enough pieces installed on my F-12 machine that this was the only
remaining compilation failure that I ran into.  Let me know if we need
an alternate patch that solves dnsmasq more gracefully than just
crippling one function.
