Log message:
json-glib: remove now redundant test target

Now that adam@ has added a generic test target to meson's build.mk,
we can just rely on that, instead.

Log message:
Rename py-meson to meson.

The motivation is to consider meson as an application, so there is only
one copy on the system, and as a python 3 program, it can build python 2
packages.

Log message:

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
