[notmuch] [PATCH] notmuch: improve installation of emacs mode

[Jeffrey C. Ollie]

1) Add a separate install target to install emacs mode.

2) Don't hardcode the installation directory, instead use emacs'
   pkg-config module.

3) Install a byte compiled version of the emacs mode.

4) Install the emacs mode in emacs' site-start directory so that it
   gets loaded automatically.
