fix BSD ldconfig handling (#9631)

For libraries installed to libdir, it's not expected to have rpath
hooked up. But for non-default libdirs, the path might not get searched
by default. `ldconfig -m <libdir>` is convenient here, as it will
programmatically add a new directory to search for shared libraries, so
the resulting installed programs work out of the box.

Include the dragonfly BSD platform name, which doesn't match the 'bsd'
catch-all pattern.
