Synopsis: Missing KDTRACE_HOOKS in Xen kernels

State-Changed-Why:
If I recall correctly, on analysis of PR 57535 (which I foolishly
neglected to write down there), the Xen kernel doesn't get loaded with
CTF data, which makes dtrace much less useful.  So that really needs to
be fixed first.

Specifically (going off vague memory), I think the kernel image that
xen_init_ksyms passes through to ksysm_addsyms_elf, whose parameters
have been set up in locore.S, is missing a .SUNW_ctf section.

Need to look closer into this -- it's been a while since I looked at
this and I don't seem to have written it down contemporaneously.
