bsp/nordic_pca10095_net: Increase image size to 192KB

Original 100KB flash size may not be enough if a lot of mynewt/nimble
features are included in build.
Secondary slot was moved to application flash before so there is a lot of unused
space in net core flash that is now assigned to primary slot.
