You may want to read my last comment in the FPC ticket, which tries to
address this a bit:

https://fedorahosted.org/fpc/ticket/490#comment:10

But some more info on this ...

If you want to have bash installed in the build root, these are the
packages which gets in:

Start: dnf install

You see that glibc is there, so it will be probably always installed.
But mock cannot successfully prepare the build root:

Complete!
Finish: dnf install
ERROR: Could not find useradd in chroot, maybe the install failed?

Adding shadow-utils and hence useradd command, these are the package
you'll get installed:

Start: dnf install
