IPS distro-import changes needed for X packages for nv_139

[Alan Coopersmith]

No changes in the core X packages in Nevada build 139 will need updates to
the IPS distro-import package definitions for those packages. However,
John Martin has provided updates to the nvidia-graphics manifest which
have been forwarded to David already.

As usual, this only lists the changes that need distro-import changes,
the full list of X changes in these builds can be seen at:
