Check libvirtd based on /proc instead of /var/run
Change libvirtd check to look for pre-existing libvirt processes on the host based on /proc, which is more reliable than pidfiles written under /var/run/ which may be stale or may not be written at all. Change-Id: I8a08dc7930c15ae90e1c6fb8a5fa3344cca2380f Closes-Bug: #1715702
