We only install FMPs if a CapsuleUpdate is requested.  Since we now have an
ESRT table which relies on FMPs to build the required information,  it
makes more sense to unconditionally install them. This will allow userspace
applications (e.g fwupd) to make use of the ERST and provide us with files
we can use to run CapsuleUpdate on-disk
