Refactor creation of logscript

Instead of using interpolation and here-strings, write function that
renders mustache template. This approach makes code cleaner and more
scalable.

  * data/logscript: add mustach template of 'log/run' script, that is
    installed when "logscript" option in effect.

  * Makefile: set DH_RUNIT_DATADIR variable in "check" target. This way,
    templates from ./data/ directory are used, not from system location.

  * debian/control: add dependency on Text::Hogan library --
    implementation of "mustache" templating standard.

  * dh_runit(template_from_data_directory): new function

  * dh_runit: install 'log/run' with "template_from_data_directory"
    function.

  * t/928935.t: check that "logscript" option correctly creates
    'log/run' script, with correct permissions.
