Subject: git: add .gitattributes file (#13947)

Add a line to .gitattributes so that `git grep -p` shows function names
properly for `*.py` files.  Without this, the class name is shown instead
of the function for python files.

This also causes diff output to use proper functions as hunk headers in
`diff` output.

Here's an example with `git grep -p`.

Before:

    $ git grep -p spack_cc var/spack/repos/builtin/packages/athena
    var/spack/repos/builtin/packages/athena/package.py=class Athena(AutotoolsPackage):
    var/spack/repos/builtin/packages/athena/package.py:            env.set('CC', spack_cc)
    var/spack/repos/builtin/packages/athena/package.py:            env.set('LDR', spack_cc)

After:

    $ git grep -p spack_cc var/spack/repos/builtin/packages/athena
    var/spack/repos/builtin/packages/athena/package.py=    def setup_build_environment(self, env):
    var/spack/repos/builtin/packages/athena/package.py:            env.set('CC', spack_cc)
    var/spack/repos/builtin/packages/athena/package.py:            env.set('LDR', spack_cc)

Here's an example with `diff`.
