scripts/config: replace hard-coded script name by a dynamic value
The script `config' prints its name in usage() function. It is currently hard-coded to value `config'. However, the script may be reused under a different name in contexts other than the Linux Kernel. Replace the hard-coded value `config' by the name of the script at runtime.
