Add Emacs configuration files

This adds a configuration file ".dir-locals.el" for Emacs to the topmost
directory of the Valgrind source tree, and another such file to the
directory drd/tests.  These files contain per-directory local Emacs
variables.

The following settings are performed:

* The base C style is set to "Linux", indentation is set to 3 columns
  per level, the use of tabs for indentation is disabled, and the fill
  column is set to 80.

* The source files in drd/tests use 2 instead of 3 columns per indentation
  level.
