bug#39377: guix search reports bad location for bytestructures

[Matt Wette <matt.wette@gmail.com>]

I'm using guix-1.0.1 on Fedora 30, x86_64.

I wanted to get module spec for bytestructures, but failed:
location points to (guix packages), but it's actually in (gnu packages 
guile).

$ guix search bytestructures
name: guile3.0-bytestructures
version: 1.0.7
outputs: out
systems: x86_64-linux i686-linux
dependencies: autoconf@2.69 automake@1.16.1 guile-next@3.0.0 
pkg-config@0.29.2
location: guix/packages.scm:880:11

synopsis: Structured access to bytevector contents for Guile
description: Guile bytestructures offers a system imitating the type 
system of
+ the C programming language, to be used on bytevectors.  C's type 
system works
+ on raw memory, and Guile works on bytevectors which are an abstraction 
over
+ raw memory.  It's also more powerful than the C type system, elevating 
types
+ to first-class status.
