[OE-core] [PATCH 1/2] pixbufcache: Ensure sysroot dependencies are satisfied

[Kyle Russell]

Reverts part of b411085fefc8582d24c172db5f6610705eb44c2f

Makes sure gdk-pixbuf-native populates the sysroot during setscene;
otherwise, gdk-pixbuf-query-loaders may not actually be available at the
time the completion function runs, causing a build failure.

Similarly, packages providing loader libraries should append to
PIXBUFCACHE_SYSROOT_DEPS with their runtime dependencies.
