classes/populate_sdk_ext: remove unnecessary dependencies breaking SDK_TARGETS

Up until recently it was possible to set SDK_TARGETS to include a native
recipe you wanted installed into the sysroot when installing the eSDK.
I'm not sure what happened but now when you try to add a native recipe
to SDK_TARGETS you get a missing task error because this recipe has no
do_package_write_* task. Of course such a task dependency is erroneous
and is apparently caused by setting SDK_RDEPENDS. I've checked and it
turns out that we no longer need to set SDK_RDEPENDS anyway (probably
because we explicitly set up task dependencies further down in the
class, which I don't think we were fully doing in early versions of the
eSDK). Thus, drop setting this variable to restore the functionality.
