daemon: Try to execute derivation builders only for matching OS kernels. 
Fixes <https://bugs.gnu.org/43668>.

Previously, guix-daemon would try to run GNU/Hurd executables on
GNU/Linux.  execve(2) would succeed, but the executable would
immediately crash.

This change prevents it from attempting to execute "i586-gnu" code on
"*-linux", while preserving the binfmt_misc-friendly behavior
implemented in commit 7bf2a70a4f.

* nix/libstore/build.cc (sameOperatingSystemKernel): New function.
(DerivationGoal::runChild): Call 'execve' only when
'sameOperatingSystemKernel' returns true.
