par/innovus revert gds.gz output gds extension

[daniellovell]

While I understand this is space-efficient to export the final database as a .gds.gz, this change (introduced in 5e3cfb3 ) significantly breaks the hammer-intech22-plugin fill.mk and icv.mk scripts. See the image below regarding how it breaks the plugin.

This PR reverts the change, so Innovus will export a .gds instead of .gds.gz

The fix could occur on either the hammer-intech22-plugin side, or here. I leave that to the maintainers to decide which is best ;)

Yes, I agree with this. For our last couple of tapeout, I had to do this in my local repo.
We can change it in main hammer. I don't see a major problem with it.
