d/rules: shlibdeps: dereference symlinks before matching

We are about to adopt the dh sequencer, which rules dh_link before
dh_shlibdeps.  This means that this rune detects the xacpi-simple
symlink, which isn't handled by the case.

Rather than adding duplicate entries, call readlink and match on the
results.
