createrepo-native: update dependency

"RDEPENDS_${PN}_class-native" doesn't work for native recipe because no
-native package will be created. Then the dependencies listed here are
not built when bitbake createrepo-native.
Update and use DEPENDS_class-native instead.

populate_sdk_base.bbclass: Allow installation of ix86 SDK on x86_64 host

Commit c04f5435 "populate_sdk_base.bbclass: use SDK_ARCH instead
of SDKMACHINE" prevents not only the installation of 64 bit SDK
configurations on 32 bit hosts (which indeed cannot work), but also
the legitimate installation of a 32 bit SDK on a 64 bit host.

Fix this.

While there, also make sure we use the same patterns ("i[3-6]86" resp.
"x86[-_]64" to get unified strings for both INST_ARCH and SDK_ARCH.
