I'm not sure where best to say this in the series so I'll try here. I
think we should name the hush.c file being imported from busybox as
"cli_hush_upstream.c" and the u-boot glue file around it as
"cli_hush_modern.c". Then instead of "CLI_HUSH_2021" etc,
"CLI_HUSH_MODERN" and then in due time, we drop CLI_HUSH_OLD and rename
CLI_HUSH_MODERN to CLI_HUSH.

This patch is also where we should make the one line removal of
"# undef CONFIG_FEATURE_SH_STANDALONE" from the upstream file, for CI.
