afm-unit.conf: Refactor its generation

The process of generating the file /etc/afm-unit.conf
had be reworked to be more straight forward.

Before that commit, a manual operation (a "make") had
to be done before committing the repository. This was
not efficient, error prone and kept temporary files in
conf.

That commit changes it by calling m4 through cmake.

+; File:
+;
+;    afm-unit.conf
+;
+; Mode:
+;
+;    ON_AGL_DEVEL(DEVEL, RELEASE)
+;
+; Role:
+;
+;    Configure how installation of widget produces unit files for systemd
+;
+; Processing and format:
+;
+;    1. File load
+;
+;           Lines beginning with ; are firstly removed
+;
+;    2. File instantiation
+;
+;           Mustache (extended) substitutions are applied using JSON
+;           data deduced from config.xml file of the widget.
+;
+;    3. Extraction of units
+;
+;           Extract produced units, pack it (remove empty lines and directives)
+;
+; Directives:
+;
+;    Any directive occupy one whole line starting with %
+;
+;     - %nl
+;
+;             produce an empty line at the end
+;
+;     - %begin systemd-unit
+;     - %end systemd-unit
+;
+;             delimit the produced unit
+;
+;     - %systemd-unit user
+;     - %systemd-unit system
+;
+;             tells the kind of unit (user/system)
+;
+;     - %systemd-unit service NAME
+;     - %systemd-unit socket NAME
+;
+;             gives the name and type of the unit
+;
+;     - %systemd-unit wanted-by NAME
+;
+;             tells to install a link to unit in the wants of NAME
+;
+; Setting variables:
+;
+;    AFM uses the feature of systemd that completely ignores options prefixed
+;    with X-
+;
+;    Consequently, options starting with X-AFM- are recorded as public data
+;    about the application and options starting starting with X-AFM-- are
+;    recorded as private data.
+;
+;    Examples:
+;
+;        X-AFM-description={{description}}
+;
+;              Records the description of the unit in the field "description"
+;              of both the public and private object describing the unit.
+;
+;        X-AFM--wgtdir={{:#metadata.install-dir}}
+;
+;              Records the installation directory path in the field "wgtdir"
+;              of the private object only.
