bug#20039: jack2: Dangling .so references

[Taylan Ulrich Bayırlı/Kammer]

While looking into another issue, I happened to notice dangling .so
references in some executables in Guix packages.  This is the first in a
series of bug reports for each such package.  Some might be false
positives; Mark suggested I report them all so we have a list to go
through.  It's also not comprehensive because of course I don't have
every Guix package installed; the script to go through one's /gnu/store
to get output such as the following for each package is attached at the
bottom of this mail.

That would be references to libjack, libjacknet, and libjackserver.
