Even though this script is expected to be sourced instead of
executed on its own, the #!/bin/sh line provides simple
documentation about what format the file is in.
In particular, the lack of such a line was confusing the
valgrind support of our test scripts, which assumed that any
executable without a #!-line should be intercepted and run
through valgrind. So during valgrind-enabled tests, any
script sourcing this file actually sourced the valgrind
interception script instead.

The valgrind script could perhaps be a bit smarter instead, but checking
#!-lines is nice and simple, and this change makes other programs like
"file" happier, too.
This problem has been around since 21d0ba7 (difftool/mergetool: refactor
commands to use git-mergetool--lib, 2009-04-08), released in v1.6.3. But
since it is only about our internal tests, and even then only about
running them with valgrind enabled, I don't know if it is worth a fix on
'maint'.
