Assigning a string to an array which is too small to include the NUL
byte at the end causes a warning on some compilers. But this function
also has some other oddities like the 'header' array which is only ever
used within sizeof().
Tidy up the function by removing the 'header' array, allow the NUL byte
to be present in git_sha_header, and calculate the length directly from
git_sha_header.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
