appliance: Fix searching for shared libraries on usr-merged Debian systems

If /lib is a symlink to usr/lib, paths to shared libraries as
determined by ld.so may differ from dpkg's file lists.

We turn the filename search pattern into a glob expression by
prefixing it with a '*', so the required packages are found again:

$ dpkg -S /lib/x86_64-linux-gnu/libpcre2-8.so.0
dpkg-query: no path found matching pattern /lib/x86_64-linux-gnu/libpcre2-8.so.0
$ dpkg -S */lib/x86_64-linux-gnu/libpcre2-8.so.0
libpcre2-8-0:amd64: /usr/lib/x86_64-linux-gnu/libpcre2-8.so.0
