dc242d3631 Plugin cpu: fix handling of more than ten CPUs
Previously only CPU entries with a single digit (0..9) were parsed.

count, since the combined entry ("cpu" without digits) is skipped.

f4518e5375 Change name of executable from "munin-node" to "muninlite"
Previously MuninLite tried to create a drop-in-replacement for
munin-node by using the same name.  But MuninLite behaves differently
and may even be used in parallel to a regular munin-node setup on a host,
thus it should use a distinct name.
