Install findutils so lcov will work in the openSUSE image

See https://bugzilla.opensuse.org/show_bug.cgi?id=1194671 - openSUSE's
lcov package lacks a dependency on findutils, but lcov's scripts use
find(1) to gather *.gcno files from the build.  Findutils is not
installed in an opensuse/tumbleweed image by default.
