kallsyms: fix escaping of NUL char in strings

The current kallsyms code is using \\0 to escape the backslash in the awk
code, but the shell too needs escaping.  This way we make sure gcc is
passed the \0.  Then gcc itself will consume this as an octal, so we have
to use 000 so gcc will create the final NUL.
