base-files: change default root shell to bash

as bash is no longer dynmaically linked against readline, there
shouldn't be any issue with making the default shell for the root user
to bash.

this should have no automatic effect on most existing systems, as
/etc/passwd is a conf file and almost everyone one will have edited it
at some point. users can resolve the .new and add it if they wish.

this does NOT change the default /bin/sh to bash. that is still dash.
