[PATCH] fix ioemu build

[Christian Tramnitz <chris.ace@gmx.net>]

Hello,

apparently the xen-setup script in ioemu tries to delete non-existant 
files which currently causes gentoo live-ebuilds to fail (I can't patch 
because the ioemu tree is being dynamically populated using git).

Anyway checking for the existence of a file before actually deleting it 
shouldn't really hurt...

This lives as patch in funtoo for a while, but as mentioned before 
patching doesnt work with live ebuilds so I'd prefer this to be fixed in 
ioemu.


Thanks,
    Christian
