cubicweb-leaflet #14813181 do not include all files in spec [validation pending]

our spec files conflict with filesystem package in centos7: we set permission 755 for /usr/bin and /usr/lib whereas filesystem set it to 555. So to be compatible with both centos7 and others we simply ignore theses directories
