[PATCH 08/15] scripts/config: replace hard-coded script name by a dynamic value

From: Clement Chauplannaz <chauplac@gmail.com>

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.
