relocate_sdk.py: ensure interpreter size error causes relocation to fail

If there is insufficent space to change the interpreter, we were
printing an error here but the overall script did not return an error
code, and thus the SDK installation appeared to succeed - but some of
the binaries will not be in a working state. Allow the relocation to
proceed (so we still get a full list of the failures) but error out at
the end so that the installation is halted.
