fortran: remove use-mpi-tkr

this is only needed by very old compilers and
is not worth maintaining.

sanity checked with:

intel-classic 2021.10.0
intel-oneapi 2023.2.0
nvhpc Cuda compilation tools, release 12.5, V12.5.82
gcc 8.5.0
gcc 4.9.1
gcc 13.2.0

unfortunately I was unable to build gcc 4.8.5 so that wasn't covered.

I don't have access to a NAG compiler anymore so that wasn't tested either.
