The files generated by gen_header.py capture the source path to the
input files and the date. While that can be informative, it varies
based on where and when the kernel was built as the full path is
captured.
Since all of the files that this tool is run on is under the drivers
directory, this modifies the application to strip all of the path before
drivers. Additionally it prints <stripped> instead of the date.

The files generated by gen_header.py include the source path to the
input files and the build date. While this information can be useful,
it inadvertently exposes build system configuration details in the
binaries. This hinders binary reproducibility, as the output will
vary if the build environment changes.
