libpam: be more strict about user's sanity

* replace do_pam_sanity function with distro_features_check inherit
* fixes:
  WARNING: libpam-1.3.0-r5 do_pam_sanity: Building libpam but 'pam' isn't in DISTRO_FEATURES, PAM won't work correctly
  in world builds and prevents user to build libpam at all without pam
  in DISTRO_FEATURES, I don't see any users of this which wouldn't respect
  pam in DISTRO_FEATURES
* only libuser is depending on libpam without respecting DISTRO_FEATURES
* there are few recipes in meta-oe layers depending on libpam without
  respecting DISTRO_FEATURES, I've sent patch for them:
  samba, openwsman, pam-ssh-agent-auth, sblim-sfcb, passwdqc, python-pam, smbnetfs
  and omxplayer in meta-raspberrypi, I've sent PR for that one:
  https://github.com/agherzan/meta-raspberrypi/pull/192
* poky-lsb will need to add pam to DISTRO_FEATURES in order to build
  packagegroup-core-lsb
