base-files: Drop /bin/sh dependency

Remove /bin/sh from bash RPROVIDES as this has a side-effect which
confuses rpm package manager when also busybox provides /bin/sh and
base-files depend on /bin/sh . The problem is broken down below.

First, bash depends on base-files and bash pkg_postinst must run
after base-files was installed, because it requires /etc/shells
provided by base-files to be in place.

Second, base-files depends on /bin/sh, which is provided by either
bash or busybox in this case. This is the actual problem here, if
bash is selected as /bin/sh provider, then there is cyclic dependency
between bash and base-files, and that confuses dnf which may install
the packages in the wrong order, bash first and base-files second .

To make this worse, if busybox is also /bin/sh provider, it can and
does happen that some systems pick busybox as the /bin/sh provider,
while others pick bash as the /bin/sh provider, and that cyclic
dependency does not always appear.

Attempt to break this dependency, remove pre-inst script from the
base-files recipe, which removes its dependency on /bin/sh and
allows it to be installed very early, and always before bash.
