emacs: make sure native compilation output dir is in $out
Native compilation output dir is the first writable one specified
by native-comp-eln-load-path[1]. The first[2] dir in
native-comp-eln-load-path is in $HOME. In the nix build sandbox,
$HOME normally does not exist so this first dir is not writable. The
second dir is in $out and thus is writable. So it is chosen as the
native compilation output dir.
Some packages, such as auctex[3], needs a writable $HOME when being
compiled. To avoid compilation error, it is necessary to create a
writable $HOME. To make sure native compilation output dir is in
$out, we can make the first dir of native-comp-eln-load-path, the one
in $HOME, read-only. Or we can explicitly choose the second dir.
This patch use the second explicit method.
