meta-ibm: use machine overrides instead of distro

Using a distro feature here might be a case of too much abstraction.
Instead, just enable them because that is what is desired for those
systems.  This is slightly easier to comprehend.

Revisit, if at a later time, several phosphor-software-manager users
enable signature verification and file syncing when using UBI (making
the abstraction useful).  If/when that occurs, those configure options
and packages should be enabled via the distro feature in the base
recipe and not in a bbappend.
