[PATCH] lib/bb/runqueue: avoid marking runtime dependencies as covered

[Paul Eggleton <paul.eggleton@linux.intel.com>]

The code which populates setscene_covered list was adding a task to the
covered list if all of the tasks that depend upon it were also covered;
however, this means that tasks that would have installed "runtime"
dependencies were being marked as covered also, e.g. gmp-native and
mpfr-native are needed by gcc-cross at runtime since they are shared
libraries that gcc links to, but their do_populate_sysroot tasks were
being marked as covered, resulting in failures later on if gcc-cross was
available from sstate but mpfr-native and gmp-native weren't.

Since we currently have no real way to handle runtime dependencies for
native packages, add a workaround which avoids marking tasks as covered
if one or more of their revdeps are from a different recipe.

Fixes [YOCTO #1536].
