But where to get generic_portrait_infantry.bmp?

.../...

Adamant has such a file in its Pictures\Race Generic folder. I believe it is different from the one in Proportions.

Or, you culd leave the file out of your mod and just instruct ppl to download the neo-expansion pack from my website. It contains a generic infantry pic, as well as infantry and other neostandard pics for numerous stock races.
