Fix incremental build of dtrace probes.

Currently dtrace(1) -Go does not properly rebuild the target if it
exists.  It results in missing symbols.

  dtrace -C -x nolibs -G -o usdt.o -s /root/git/freebsd/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/json/usdt.d tst.usdt.o
  dtrace: target object (usdt.o) already exists. Please remove the target
  dtrace: object and rebuild all the source objects if you wish to run the DTrace
  dtrace: linking process again
  cc -O2 -pipe -O0 -g -I/root/git/freebsd/cddl/usr.sbin/dtrace/tests/common/json -std=gnu99 -fstack-protector-strong -Qunused-arguments  -o tst.usdt.exe.full tst.usdt.o usdt.o
  tst.usdt.o: In function `main':
  /root/git/freebsd/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/json/tst.usdt.c:56: undefined reference to `__dtrace_bunyan_fake___log__debug'
  /root/git/freebsd/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/json/tst.usdt.c:60: undefined reference to `__dtrace_bunyan_fake___log__debug'
  cc: error: linker command failed with exit code 1 (use -v to see invocation)
  *** [tst.usdt.exe.full] Error code 1

This is a consequence of r212358.
