2.1.19p1 misidentifies if server is VMWare ESX

[Jamie McKnight]

During testing of 2.1.19p1 I noticed that the class VMWare_ESX was defined
on a machine that was not an ESX image or server.  Looking at misc.c, it
appears that if you can stat /etc/issue, cfengine defines the VMWare_ESX
class.

src/misc.c:

836 if (stat("/etc/issue",&statbuf) != -1)
837    {
838    Verbose("\nThis appears to be a VMWare ESX system.\n");
839    AddClassToHeap("VMWare_ESX");
840    ESX_version();
841    }

Shouldn't that be checking for the existence of the VMware-esx rpm, or the
existence of the /etc/vmware directory, and not relying on stat'ing
/etc/issue?  We drop /etc/motd and /etc/issue files on every host that
print out a big warning banner.

If I need to provide more info please let me know.
