[PATCH] checkpatch: Improve EMBEDDED_FILENAME test

[Joe Perches]

Privately, Heinz Mauelshagen showed that the embedded filename test
is not specific enough.

> WARNING: It's generally not useful to have the filename in the file
> #113: FILE: errors.c:113:
> +            block < registered_errors.blocks + registered_errors.count;

Extend the test to use the appropriate word boundary tests.
