Revert "relocate_sdk.py: remove hardcoded SDK path"

This reverts commit 6671a4d980c8bef8f402780a308f6c43a25044aa.

This breaks uninative tarball since the call of relocate_sdk.py from uninative.bbclass
wasn't updated to account for this change. It isn't clear what value that code could
pass in and this isn't simple to fix so revert until a better fix can be found
that doesn't break uninative.
