fujitsu-mpi package: help CMake find wrappers (#43979)

Browse Source 
Set MPI_C_COMPILER etc. env vars when building with fujitsu-mpi, which
override CMake logic. Without using these variables to explicitly
request the Fujitsu MPI wrappers, the builtin CMake logic is unwilling
to use these wrappers unless the Fujitsu compiler is used, but they
should be used for %clang as well.

This avoids patching CMake module files like in #16864, primarily to
avoid the possibility of altering behavior for specs that do not use
%fj or ^fujitsu-mpi.
