Added missing dependency to typelib

[m0rsch1]

This is a commit back from xrock_gui_model/bin/xrock-resolve-ports to change back to rock-instantiate.
Don't know if this is needed but it has been flagged as a fix by @malter

I've openend the pull-request to possibly merge back.
But i am not yet sure if this is needed any why it had been inserted.

Can't tell either if this is necessary. Opinions? @maltewi (and maybe @pierrewillenbrockdfki)

If i got that right, this is the definitions of Orocos.apply_conf:
tools/orocos.rb/lib/orocos/configurations.rb: def self.apply_conf(task, path, names = ['default'], overrides = true)
The change just explicitly sets the overrides variable to its default.

I don't see where rock-instantiate would need typelib present. This is not c++ where you need to have the header present to inspect an object, and the inspection is done in another ruby file anyways.

Well, the 'true' flag at the end is indeed just stating the default, but well the default might change :)
However, i think, the typelib requirement is the change of interest here.
But i dont know if its needed or not but @malter added it with the commit message
"Added missing require for xrock-resolve-ports" which is a copy of rock-instantiate.
Maybe some complex port type cannot be converted from a dynamic to a 'normal' port without it?

I guess if the require is needed somewhere else, it should be where it is needed.

If you currently don't have anything that breaks without this, I would close this for now. Feel free to re-open once you can reproduce an issue (or if @malter can clarify the need for this).
