Hannu Nyman d674422a81 busybox: update to 1.28.2
Update busybox to 1.28.2, refresh patches and default config.

* modify 230-add_nslookup_lede.patch as opt_complementary was removed
    Also move nslookup_longopts variable declaration to be inside
    the same conditional as the function itself.
* modify 250-date-k-flag.patch to match upstream (opt_complementary)
* remove 600-cve-2017-16544.patch that is upstreamed

Notes about config changes:
* Some applet-specific LONG_OPTIONS config options were removed
* Config help text indentation changed, caused lots of
  text formatting changes for convert_menuconfig.pl
* convert_defaults.pl moved lots of defaults around, summary of
  actual changes below
