man-pages: respect api-documentation

* let manpages.bbclass to enable manpages PACKAGECONFIG based on
  api-documentation DISTRO_FEATURES
  PACKAGECONFIG_append_class-target = " ${@bb.utils.contains('DISTRO_FEATURES', 'api-documentation', 'manpages','', d)}"
* it's true that building man-pages without manpages being enabled
  doesn't make much sense, but it's included through couple
  packagegroups:
  meta/recipes-core/packagegroups/packagegroup-self-hosted.bb:    man-pages \
  meta/recipes-extended/packagegroups/packagegroup-core-lsb.bb:    man-pages \
  or in world even for people who might not be interested
  in man-pages
