    plugins: Fix the PeasEngine search path
    
    This commit reverts part of commit 632f98e9 so the "datadir" variable is
    set correctly for plugins. Otherwise for example autotools-templates
    tries to find resources in
    ".../plugins/autotools_templates/resources/..." rather than in
    ".../plugins/autotools-templates/autotools_templates/resources/..." and
    of course fails.
