difftool: provide basename to external tools
Currently, only configured diff helpers get the basename of the file being compared. Tools specified with "git difftool -x" only get the names of temporary files for the different versions. Export BASE so that an external tool can read the name from the environment. Rather than using a third argument, this avoids breaking existing scripts which may somewhat carelessly be using "$@" rather than "$1" "$2".
