add options when explicitly invoking dynamic loader

so far the options are --library-path and --preload which override the
corresponding environment variables, and --list which forces the
behavior of ldd even if the invocation name is not ldd. both the
two-arg form and the one-arg form using an equals sign are supported.

based loosely on a patch proposed by Rune.
