7258fdd7d7 tty: vt: conmakehash: remove non-portable code printing comment header
Commit 6e20753da6 ("tty: vt: conmakehash: cope with abs_srctree no
longer in env") included <linux/limits.h>, which invoked another
(wrong) patch that tried to address a build error on macOS.

According to the specification [1], the correct header to use PATH_MAX
is <limits.h>.

The minimal fix would be to replace <linux/limits.h> with <limits.h>.

However, the following commits seem questionable to me:

 - 3bd85c6c97 ("tty: vt: conmakehash: Don't mention the full path of the input in output")
 - 6e20753da6 ("tty: vt: conmakehash: cope with abs_srctree no longer in env")

These commits made too many efforts to cope with a comment header in
drivers/tty/vt/consolemap_deftbl.c:

  /*
   * Do not edit this file; it was automatically generated by
   *
   * conmakehash drivers/tty/vt/cp437.uni > [this file]
   *
   */

With this commit, the header part of the generate C file will be
simplified as follows:

  /*
   * Automatically generated file; Do not edit.
   */

BTW, another series of excessive efforts for a comment header can be
seen in the following:

 - 5ef6dc08cf ("lib/build_OID_registry: don't mention the full path of the script in output")
 - 2fe29fe945 ("lib/build_OID_registry: avoid non-destructive substitution for Perl < 5.13.2 compat")

6e20753da6 tty: vt: conmakehash: cope with abs_srctree no longer in env
conmakehash uses getenv("abs_srctree") from the environment to strip
the absolute path from the generated sources.
However since commit e2bad142bb ("kbuild: unexport abs_srctree and
abs_objtree") this environment variable no longer gets set.
Instead use basename() to indicate the used file in a comment of the
generated source file.

3bd85c6c97 tty: vt: conmakehash: Don't mention the full path of the input in output
This change strips $abs_srctree of the input file containing the
character mapping table in the generated output. The motivation for this
change is Yocto emitting a build warning

        WARNING: linux-lxatac-6.7-r0 do_package_qa: QA Issue: File /usr/src/debug/linux-lxatac/6.7-r0/drivers/tty/vt/consolemap_deftbl.c in package linux-lxatac-src contains reference to TMPDIR

So this change brings us one step closer to make the build result
reproducible independent of the build path.

scripts/conmakehash is only used for generating

Move it to the related directory.
