bash: Don't become the default /bin/sh
bash: Don't become the default /bin/sh

Our upstart conf files don't work with /bin/sh set to bash -- apparently
it handles quotes on the command line differently from the ash supplied
by busybox. Prevent a /bin/sh symlink to bash from being created by
adding a .bbappend file for bash that unsets the ALTERNATIVE_* variables
set in bash.inc .

[OWEBOS-2550] bash can not be the default /bin/sh
