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.
Fixes: b18b047002b7 ("kbuild: change scripts/mksysmap into sed script")
