Revert "[Untest] Replace all the use of g96 module to trr module"

This reverts commit f7d13e3544d762731e134041386c06ec2124dff0.

gfortran on gamma is too old to support trr module,
and ifort (maybe) is so old that run-time segmenation error
would occur in MPI program.

Anyway, now fall back to use g96 for all programs, instead. (sigh)
Change all the rest programs to use g96

... due to the old compiler version on gamma
