Add fftpack to EXTRA_DIST

The new fftpack files added by 51c2f6c are only compiled if
fftpack is used. Thus "make dist" does not included those
by default.

Fix CUDA_HOST_COMPILER flag name

Fixes #1143

Change-Id: If34f27aa8fa73420ac85d4ec6997e8ebe78261d4
use legacy CUDA non-bonded kernels only on Fermi

This solves a remainig todo as well as clarifies some variable naming
and documentation.

Fixed the MPI recognition string in g_tune_pme

Since the identifying string "NNODES="is not printed any more by MPI-enabled
mdrun, we now use the "MPI library:" string instead.

Added extra check in for setaffinity support.

The Linux version of tMPI_Thread_setaffinity_support() did not check
whether pthread_setaffinity_np() would actually work on the system
it's running on. It now checks by running pthread_getaffinity_np()
and checking its return value.

This is relevant for, for example, Bluegene systems which don't
support explicit affinity setting.

Re-generated group kernels

This should be a null operation, but I had to fix copyright
years in python scripts and it had the following effects:
* removed some debugging printf statements in GB C kernels
* minor whitespace change now consistent between template and output
