ctf: change the name of the CTF section in kernel modules
Since we have broken backward-compatibility with Solaris libctf and changed the
magic number in CTF files, we should change the name of the section they are
written to. .dtrace_ctf seems like a good idea (which means that shared types
will now be found in the .dtrace_ctf.dtrace_ctf section, rather than, as
before, .SUNW_ctf.dtrace_ctf).
