PR#45500 benchmarks/libmicro: Add DragonFly support

This commit fixes the run-libmicro command which was broken for all
platforms.  It was pointing at the destdir version instead of the
installed version.

It also provides a DragonFly-specific makefile which enables it to
build and run on DragonFly.
