Update Layout for python portfile

[Korusuke]

Issue #5

Two blank lines feel weird but that is what works :)

[Korusuke]

This is the output after current changes:

setuptools :

if {${name} ne ${subport}} {
    depends_build-append \
                    port:py${python.version}-setuptools

    livecheck.type  none
}

upt :

if {${name} ne ${subport}} {
    depends_build-append \
                    port:py${python.version}-setuptools

    depends_lib-append \
                    port:py${python.version}-spdx-lookup

    livecheck.type  none
}

pytest :

if {${name} ne ${subport}} {
    depends_build-append \
                    port:py${python.version}-setuptools

    depends_lib-append \
                    port:py${python.version}-atomicwrites \
                    ...
                    port:py${python.version}-wcwidth

    depends_test-append \
                    port:py${python.version}-argcomplete \
                    ...
                    port:py${python.version}-requests

    livecheck.type  none
}

It indeed works, but I agree with you that it looks a little weird in the template. I would need to look a bit more at the ninja syntax if there is some other way that will give the same output - it not, I guess this would be okay.

[reneeotten]

okay, I spend an hour or so looking at the documentation and doing some trial-and-error attempts to get the newlines where we want them..... I was hoping for a more of "what-you-see-is-what-you-get" approach by putting the empty lines where we actually want them, but without much/any success ;)
There are settings in upt_macports.py that probably determine some of this stuff for the ninja2 templates, but I haven't figured it out yet.

Since your solution works, despite the slight weirdness of the two empty lines in the template, I am inclined to merge this as "it works and probably nobody is going to change this anymore". Unless @Steap has some insight and we can come up quickly with something else; otherwise let's move on and we can look at this again if we're bored!

@reneeotten Yeah, there are also a few variables (such as keep_trailing_newline) that are interesting when creating the Jinja2 environment, but I can never understand/remember how everything works.

Let's merge this :)
