Subject: [PATCH] nixos/binfmt: fix extension for Windows binaries

Extension based matching for Windows targets define it '.exe' but kernel
documentation explicitly states it should be passed "without the .".

From https://docs.kernel.org/admin-guide/binfmt-misc.html
> * magic:
>   [...] If you chose filename extension matching, this is the
>   extension to be recognised (without the ., the \x0a specials are not
>   allowed).
