symbol-check: Check requested ELF interpreter

It is important that binaries request a standard interpreter location
where most distros would place the linker-loader. Otherwise, the user
would be met with a very confusing message:

    bash: <path>/<to>/bitcoind: No such file or directory

When really it's the interpreter that's not found.
