main/busybox: upgrade to 1.29.3

* Remove all patches already applied upstream
	* 0001-ash-add-support-for-command_not_found_handle-hook-fu.patch
	* 0001-cat-fix-cat-e-and-cat-v-erroneously-numbering-1st-li.patch
	* 0001-wget-emit-a-message-that-certificate-verification-is.patch
	* 0015-ash-introduce-a-config-option-to-search-current-dire.patch
	* 0016-top-handle-much-larger-VSZ-values.patch
	* 0017-ifupdown-do-not-fail-if-interface-disappears-during-.patch
* Rename config option for command_not_found hook
	* upstream patch adding this hook slightly differs from our
	  downstream patch in this regard
* Rebase some patches manually:
	* external_ssl_client.patch
	* 0006-ping-make-ping-work-without-root-privileges.patch
	* 0007-fbsplash-support-image-and-bar-alignment-and-positio.patch
* Add support for `-e` to our ssl_client
	* See https://git.busybox.net/busybox/commit/?id=403f2999f94937ba3f37db6d093832f636815bb9
* Update the configuration file
* Regenerate all patches using `git format-patch --no-numbered --no-signature`
  to reduce the diff for future upgrades.
