Bug#285857: dpkg-dev: dpkg-shlibdeps should try adding /usr

retitle 285857 dpkg-shlibdeps should better match ldd and dpkg --search results

Another solution would be (when ldd returns /lib/libbar.so.1.0),
instead of calling dpkg --search /lib/libbar.so.1.0, to
call dpkg --search libbar.so.1.0, which will return

libbar: /usr/lib/libbar.so.1.0

and then check that /lib/libbar.so.1.0 and /usr/lib/libbar.so.1.0
really are the same file: same device, same inode.

It is possible that dpkg --search returns several results: dpkg --search
libm-2.3.2.so for instance (tls and non-tls versions). A loop would
check out which one corresponds to ldd's result.
