relocate_sdk.py: new interpreter string was not '\0' terminated

The problem: SDK binaries were not properly relocated when the SDK
was installed into a path that had a length less than the default one.
Apparently, there were two problems here: the padding was done wrong
(the size of one program header table entry was used instead of the
program section size) and the new padded string was not used at all.
