Refactoring in commit v3.6.0-rc1~72^2 (HDF5: Rework component searching
to correctly find HL for all bindings, 2016-05-12) accidentally dropped
the name `hdf5hl_fortran` from the list of library names and replaced it
with `hdf5_hl_fortran`.  IIUC the latter name is when HDF5 is built with
CMake and the former name is for other build systems.  Since this is the
non-CMake code path, user the former name.

Closes: #16233
