busybox: upgrade to stable 1.22.1

Upgrade busybox to the stable release 1.22.1.

During this upgrade, 9 patches are removed. Reasons are detailed below.

The following 6 patches are removed as they have been merged.
    meta/recipes-core/busybox/busybox/busybox-lineedit-initialize-delptr.patch
    meta/recipes-core/busybox/busybox/busybox-list-suid-and-non-suid-app-configs.patch
    meta/recipes-core/busybox/busybox/busybox-sed-fix-sed-clusternewline-testcase.patch
    meta/recipes-core/busybox/busybox/busybox-sulogin-empty-root-password.patch
    meta/recipes-core/busybox/busybox/find-get-rid-of-nested-functions.patch
    meta/recipes-core/busybox/busybox/testsuite-du-du-k-works-fix-false-positive.patch

The following three patches are removed because they are mainly about moving
binaries from /bin to /usr/bin to make the update-alternative work correctly
at rootfs time. We can easily solve this problem by changing recipes. There's
no compelling reason why such patches are needed.
    meta/recipes-core/busybox/busybox/run-parts.in.usr-bin.patch
    meta/recipes-core/busybox/busybox/stat-usr-bin.patch
    meta/recipes-core/busybox/busybox/watch.in.usr-bin.patch

-Subject: [PATCH] sulogin: allow system maintenance login if root password is
- empty
-
-The current password checking is unable to distinguish between the user
-entering an empty password or pressing Control-D. As a result, an empty
-password always results in normal startup.
-
-We modify bb_ask to return NULL if Control-D is pressed without entering
-a password. The sulogin applet is then modified to only proceed to
-normal startup if bb_ask returns NULL. This covers EOF with no password,
-interrupt by timeout and ^C.
