kbuild: explicitly run mksysmap as sed script from link-vmlinux.sh
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. The shebang can't use the env command, otherwise the "sed -f" command would be treated as a single argument. This can be solved with the -S flag, but that is a GNU extension. Explicitly use sed instead of relying on the executable shebang to fix NixOS builds without breaking build environments using Busybox.
