ecl: make sure boehmgc is available to gcc/linker

[collares]

Motivation for this change

Since #131719, maxima-ecl is built with strictDeps = true. When ecl is built with useBoehmgc = true, libgc's headers, which were previously found by virtue of boehmgc being in propagatedBuildInputs, no longer get appended to the include path. A similar thing happens for linker flags.

This PR fixes the Sage build.
