tools/xenalyze: Remove argp_program_bug_address

xenalyze sets argp_program_bug_address to my old Citrix address.  This
was done before xenalyze was in the xen.git tree; and it's the only
program in the tree which does so.

Now that xenalyze is part of the normal Xen distribution, it should be
obvious where to report bugs.
