shell: clarify help text of CONFIG_{SH,BASH}_IS_* options
Mention the behavior if user selects CONFIG_SH_IS_ASH but not CONFIG_ASH. We will be explicit that invocations like "busybox ash" will not work for such configuration. Also clarify help text of CONFIG_BASH_IS_* that bash compatibility in ash is not complete. (It shouldn't be anyway - ash can't support every bash quirk out there.)
