I figured it out - there were compounding problems here.

Firstly, the FILESPATH setting in the main recipe is wrong and
needs to be removed.  Secondly, my .bbappend override needs to
be written using ':=' like this:
   FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:${THISDIR}/${PN}:"

Now it's working fine.
