f2fs utils: set correct dependency on dynamic libf2fs

Don't link against it anymore.
Just let dlopen() deal with it correctly.
The "config" struct will come from the f2fs_ioutils
and libf2fs_fmt_host expects to have it global, so let
link with -rdynamic and let dlopen() resolve it.

Be more aggressive with linux-only builds.
