notmuch: Apply patch for libutil breakage

The current notmuch release fails to build when the system has a
libutil library. We apply a patch to fix this. The patch has already
been applied upstream so we can remove it on the next release.

+Apply patch where build fails if the system has a libutil:
+  https://notmuchmail.org/pipermail/notmuch/2017/024295.html
+Already applied upstream so we'll remove this at the next update.
+
+Apparently some systems (MacOS?) have a system library called libutil
+and the name conflict causes problems. Since this library is quite
+notmuch specific, rename it to something less generic.
