Patch by Gilles Filippini

The HDF5 configure check does not handle installations where the HDF5
libraries are built with a name suffix (e.g. hdf5_serial). As a result,
the build fails when configuring Slurm against newer HDF5 releases.
This patch detects the HDF5 library suffix from the linker flags provided
by the HDF5 wrapper and uses it when checking for the HDF5, high-level,
and Fortran libraries.
This restores compatibility with both unsuffixed and suffixed HDF5 library
layouts.
