[OE-core] comments and actual PACKAGE_CROUPs in core-image.bbclass don't match

[Robert P. J. Day]

  yes, yes, more pedantry but if one examines core-image.bbclass,
the explanatory comments for the IMAGE_FEATURES/PACKAGE_GROUP lines
don't sync up exactly (for example, no comment line for qt4-pkgs).

  i'll let someone higher up the food chain decide if that's worth
tweaking.
