[PULL 12/20] configure: fix gio_libs reference

[Paolo Bonzini]

From: Bruce Rogers <brogers@suse.com>

The gio library detection code no longer works, due to a missing $ in
front of the gio_libs reference. Make the string be $gio_libs.

Fixes: 76346b6264a ("configure: Test that gio libs from pkg-config
work")
