Jelle Raaijmakers 30abfc2b21 Kernel: Pass absolute path to shebang interpreter 
When you invoke a binary with a shebang line, the `execve` syscall
makes sure to pass along command line arguments to the shebang
interpreter including the path to the binary to execute.

This does not work well when the binary lives in $PATH. For example,
given this script living in `/usr/local/bin/my-script`:

  #!/bin/my-interpreter
  echo "well hello friends"

When executing it as `my-script` from outside `/usr/local/bin/`, it is
executed as `/bin/my-interpreter my-script`. To make sure that the
interpreter can find the binary to execute, we need to replace the
first argument with an absolute path to the binary, so that the
resulting command is:

  /bin/my-interpreter /usr/local/bin/my-script
