FindMPI: remove single quotes from include path
Intel OneAPI's MPI wraps include paths into single quotes, e.g.:
$ mpiicc -show
icc -I'/opt/intel/oneapi/mpi/2021.1.1/include' -L'/opt/intel/oneapi/mpi/2021.1.1/lib/release' -L'/opt/intel/oneapi/mpi/2021.1.1/lib' -Xlinker --enable-new-dtags -Xlinker -rpath -Xlinker '/opt/intel/oneapi/mpi/2021.1.1/lib/release' -Xlinker -rpath -Xlinker '/opt/intel/oneapi/mpi/2021.1.1/lib' -lmpifort -lmpi -ldl -lrt -lpthreadThis merge request removes single quotes when sanitizing _MPI_INCLUDE_PATH.
