relocate_sdk: fixed .gccrelocprefix section handling 

When fixing paths for .gccrelocprefix section, it will corrupt the next
entry during updating the current one if "new_prefix" length is more
than "DEFAULT_INSTALL_DIR", this problem is obvious on the code, but it's
only found when install sdk onto a net file system.
