app-alternatives/sh: support sys-apps/busybox
Note that we have to check for CONFIG_FEATURE_SH_STANDALONE=y to avoid
busybox preferring internal applets over commands in PATH.
See https://web.archive.org/web/20221206223848/https://busybox.net/FAQ.html#standalone_shell.
Closes: https://bugs.gentoo.org/888781
