FindHDF5: Tolerate failure during compiler interrogation
Check that the file that is accessed via `file(STRINGS...)` truly
exists.
This is not the case in some EMSCRIPTEN/WebASM builds where we want to
overwrite the HDF5 find logic manually. The missing check here prevents
that one can overwrite the search logic in exotic environments.
