tools/examples: Remove more obsolete content
xeninfo.pl was introduced in commit 1b0a8bb57e3e ("Added xeninfo.pl, a
script
for collecting statistics from Xen hosts using the Xen-API") and has been
touched exactly twice since to remove hardcoded IP addresses and paths.
The configuration files in vnc/* date from when we had a vendered version of
Qemu living in the tree.
These have never (AFAICT) been wired into the `make install` rule.
