[PATCH 1/1] tools: use basename to identify file in gen-mach-types

[Alexander Stein]

From: Bruce Ashfield <bruce.ashfield at gmail.com>

FILENAME is replaced by the full path to the executing script. If
the script is executed via a fully specified path, that is captured
in the output. Although it doesn't impact the output, it does trigger
reproducibility warnings/errors.

So we introduce a basename() function in the script and use it to
make sure the output file contains only the name of the awk script.
The motivation for this change is Yocto emitting a build warning
