vma-iter: Relicense under GPLv2+

[Bruno Haible]

I want to use the 'vma-iter' module in GNU libffcall, which is under GPLv2+.

This requires relicensing the module under GPLv2+ (or weaker).

Looking through the history of src/vma-iter.h, src/vma-iter.c and its
predecessor lib/get-rusage-as.c (before 2011-01-24), I am the only contributor
of legally significant changes to these files. Therefore I can do this
relicensing.
