rockinitramfs: in libexec/list-deps.sh:
only output first occurance of the required library
since we switched to glibc26, we have more symlinks in /usr/lib
for essential /lib libraries (usr/lib/libdl.so.2 -> libdl-2.6.so)
this caused list-deps.sh to output more than one occurance of the
same library
