Subject: [PATCH] Export $HOME if we have to calculate it

If $HOME is unset in the environment, fish calculates it with
getpwnam(). However, it wasn't being exported. Just like the $USER
calculation, $HOME should probably be exported, because everyone will
assume that it's an environment variable (as opposed to an unexported
global variable).
