[PATCH V2 4/4] busybox.inc: fix QA package-missing warnings

[Hongxu Jia <hongxu.jia@windriver.com>]

While building busybox with QA package-missing checking enabled,
there was warning:
...
WARNING: QA Issue: package busybox-mdev not generated, but listed in PACKAGES
WARNING: QA Issue: package busybox-httpd not generated, but listed in PACKAGES
...

The config in ${B}/.config decides to generate busybox-mdev, busybox-hwclock,
busybox-udhcpd, busybox-httpd or not. Files are copied if the packages generated.
Set PACKAGES in do_package according to the existance of these files, so we could
dynamic generate these packages according to the configuration.
