/bin/sh as a shell is punishing. There is no good reason to make
the occasional root login unpleasant.
Since /bin/sh is usually /bin/bash in compat mode, i.e. if one is
available, the other will be too, /bin/bash is almost as good as a default.
But to avoid a regression in the situation where /bin/bash (or
DEFAULT_USER_SHELL) is not installed, we check with access() and fall back
to /bin/sh. This should make this change in behaviour less risky.
(FWIW, e.g. Fedora/RHEL use /bin/bash as default for root.)
This is a follow-up of sorts for 53350c7bba,
which added the default-user-shell option, but most likely with the idea
of using /bin/bash less ;)
Fixes #24369.
