Convert the dtrace(1) man page to mdoc and fix up some aspects of it that
don't make sense on FreeBSD. In particular,

- remove the ATTRIBUTES section,
- remove references to the Solaris Dynamic Tracing Guide, except in the
  SEE ALSO section,
- update the description of the -A option for FreeBSD's implementation,
- remove references to Solaris-specific programs and configuration files,
  and replace them with FreeBSD equivalents where possible.

The content has not changed aside from this.
