nixos/kexec: Fix typo in meta.platforms
Evaluation error introduced in 599c4df46a90c7415a6cc0689f0b23d22e7fdb67.

There is only a "platformS" attribute in kexectools.meta, so let's use
this and from the code in the kexec module it operates on a list,
matching the corresponding platforms, so this seems to be the attribute
the original author intended.

Tested by building nixos/tests/kexec.nix on x86_64-linux and while it
evaluates now, the test still fails by timing out shortly after the
kexec:

machine: waiting for the VM to finish booting
machine# Cannot find the ESP partition mount point.

This however seems to be an unrelated issue and was also the case before
the commit mentioned above.
