special/dampuu: fix mistake in damping profile

Earlier damping profile was zero everywhere.

Am now also applying a ceiling to the damping profile to avoid strange
effects in the corners of the domain

special/dampuu: correctly get far-field profiles for npx*npy /= 1

For ldamp_rho and ldamp_ss

Earlier, I was just considering the profile at the left edge of the
current processor to be the far-field value. This is not correct for
npx*npy /= 1.

Would make it difficult to add more types of far-field in the future.
