nativesdk-rpm: Add wrappers for nativesdk support

When installing the SDK to a non-default path, running "rpm --showrc" from the
sdk will produce the following error:
error: Unable to open /opt/windriver/wrlinux-small/10.17.41/sysroots/x86_64-wrlinuxsdk-linux/usr/lib/rpm/rpmrc for reading: No such file or directory.

Fix this by adding wrappers that dynamically export the RPM_CONFIGDIR,
RPM_ETCCONFIGDIR and MAGIC environment variables, pointing to the proper
sdk locations.
