test-many-klibcs: Don't patch longer interpreter name into test execs
Patching in a longer interpreter name may cause the base load address
to be lower, which results in failure to map the executable on some
architectures.
Shorten the name by:
- Creating a symlink "k.so" in the build directory to klibc.so
- Using the relative filename of k.so
