Bug#983673: octave-openems: missing h5readatt_octave.cc

[g.l. gragnani]

I think the related octave library "h5readatt_octave.oct" is already 
included in Debian package.
Just try to add to the octave path:
addpath 
'/usr/lib/x86_64-linux-gnu/octave/packages/openems-0.0.35/x86_64-pc-linux-gnu-api-v55'

Regards.

G.L.G.
