configury: harden IGNORE_TKR check

NVIDIA HPC Compiler (e.g. nvfortran) incorrectly selected the GCC style pragmas to support IGNORE_TKR. Harden the test by mimicking exactly the mpi f08 bindings in order to fix that false positive. Thanks Chris Parrot for the report. Refs. #11582 Signed-off-by: Gilles Gouaillardet <[email protected]> (cherry picked from commit 600df6a)
