In commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed
script"), the mksysmap script was transformed into a sed script,
made directly executable with "#!/bin/sed -f". Apparently, the path to
sed is different on NixOS, fixed by using the env command.
To accommodate the number of arguments above the normal maximum for
hashbangs, the -S flag of env was used (as in
"#!/usr/bin/env -S sed -f"). However, env -S is a GNU extension.
Explicitly use sed instead of relying on the executable shebang to keep
compatibility with build environments using Busybox.
