[libvirt PATCH 2/2] meson: Stop looking up ZFS programs at build time

At this point, we're no longer using the availability of the
ZFS programs at build time to decide whether to enable ZFS
support, so the only purpose of these find_program() calls is
to record their absolute paths.

However, the virCommand facilities that we're ultimately using
to run them are already capable of performing this lookup at
runtime, and in fact that's exactly what we already do in the
case of, for example, vstorage.

Drop the build time lookups and always perform them at runtime.
