Update requests for packages imported from Arch Linux

[D.Dave]

Qspectrumanalyzer seems in need to be rebuilt:

Qspectrumanalyzer doesn't draw the plot/graph

I just tested and i could not make it work. Indeed, this backend and hence the package needs updating (the current version of that library is 8 not 7). But the other backands do not work too, at least in my case. I am currently usind a rtl based tv tuner with rtl-sdr and gqrx, it works.
