Fix DTrace build on Illumos
DTrace was recently patched in Illumos to fail to create an object
file if no probes are found.
* https://www.illumos.org/issues/4248
* https://github.com/illumos/illumos-gate/commit/54a20ab41aadcb81c53e72fc65886e964e9add59
This patch fixes two issues:
* Modify the configure script to pass an object file to `dtrace -G`
that actually invokes a probe.
* Remove creation of `dtrace_user.o` from the dyntrace Makefile. In a
previous commit [1] Scott Fritchie relocated all the user probes
into the VM proper due to difficulties with DTrace probes in shared
libraries. The `dtrace_user.d` file is now empty and generates a
header file with nothing in it. There is no longer any reason to
generate `dtrace_user.o` because all the probes are in the VM. Thus
all the steps for building `dtrace_user.o` have been removed.
