shadow: Fix various invalid assumptions about directory layout

The makefiles in the shadow package have their own hard-coded paths
for ${base_bindir} and ${base_sbindir} (known as "bindir" and "sbindir"
in shadow-speak).  Ensure that they install into our paths rather than
their own.

Also check that ${base_bindir} and ${bindir} are different before trying
to move files from one to the other; likewise for ${base_sbindir} and
${sbindir}.
