bsd-headers: Fix LICENCE and dev package RDEPENDS

Clear out runtime deps for dev package, since PN is empty packager will
try to resolve to PN when building images with musl and error out since
PN is deleted as its empty

musl-dev explicitly depends upon it so it will get pulled into build
in right order
