After multikernel support was added, both std and rt packages are
installed into the image, so it's confused to find the sign tools
and the source tar files during the build.
According to the ARCHVERSION, the correct path of the tools and the
source tar files kpatch-build used for the different kernel type can
be found now.
Test Plan:
Pass: build-pkgs -a -b std,rt
Pass: build-image
Pass: Verify the kpatch-build building process without errors.
