build: ector: make sure the triangular header files end up in dist

In commit 98b0408a4eed5c2beafd4f396b64ca54fb00270f the new triangulator
static_lib was introduced with ector as user. The ector Makefiles missed to
also include the header files as deps so they never ended up in the dist
failing distcheck.
