build: get rid of the sparse expand stuff

* i don't see a reason why we are doing this because we never deal
with flashing system img rawly
* This will put useless write on ssd..
* we don't have space on ssd

  silently fall-back to Gerrit.

lets make the lunch list look a little neater

It's very simple, but with more and more devices coming in, a long list won't cut it
There are probably better ways of doing this, feel free to comment

Removed extranneous export -f lines (uneccesary when calling source build/envsetup.sh and causes extra output in zsh)

envsetup: add a helper to fix "out/target/common" not being really common

* out/target/common isn't really common, and if you do
  back to back builds for multiple devices, that is noticable.
* Use out/target/common-$device instead, and link the appropriate
  dir to out/target/common every time lunch() is run, if
  CM_FIXUP_COMMON_OUT is set.
* Refer https://groups.google.com/forum/#!topic/android-building/ispbOgzoyg8
  for more info.
