MPC must update to latest Orbit dependencies for M1

[merks]

When MPC and ECF are installed together, as is the case in all EPP product, there is a linkage error as reported in this issue:

https://github.com/eclipse/ecf/issues/116

Specifically this is the first error in the log:

In such an installation, it's not possible to use p2 for updates or installs.

@jonahgraham

This is effectively a stop ship problem for M1.

[jonahgraham]

I see https://github.com/eclipse-mpc/epp.mpc/pull/11 merged. Is there anything else to do (besides contributing the fixed MPC to SimRel)?

[merks]

I tested locally with a local mpc build that the duplicates were eliminated so I’m quite confident that a new contributed version will fix the problem.

Ideally ecf could be updated too

I can confirm that with the latest staging build with this MPC contribution:

the linkage problem is fixed.
