Joachim Wiberg 81cb90804e test: include bundled helpers' libraries in the sysroot
keventd links libblkid, which finit itself does not, but sysroot.mk
only copied the libraries finit links.  Inside the sysroot keventd
then fails to start:

    Service keventd[18] died (exit status: 127)

Collect libraries from finit and everything installed under
libexec/finit/ instead.
