bug#51086: tlp error in tlp-func-base

[Alex Devaure <ajadevaure@gmail.com>]

Hi,
During the system boot, tlp generates an error:
/gnu/store/68mpiffl51mcrss7zy26dnqfx3d5v2vv-tlp-1.4.0/share/tlp/tlp-func-base:
line 528 /usr/share/tlp/bat.d/[0-9][0-9]*[a-z]: No such file or
directory.

It looks that the path to the bat.d directory is not modified during the
package creation. I think that the following patch should fix the
problem:
diff --git a/gnu/packages/linux.scm b/gnu/packages/linux.scm
