[PATCH openbmc v3] initfs: Store whiltelist in a directory of files

[OpenBMC Patches]

From: Milton Miller <miltonm at us.ibm.com>

Change the whiltelist definition to be files in a directory instead
of a single file.  This will allow us to store which files should
be saved in individual recipes and also supports comments in the
whitelist.

The actual split into separate files is deferred for prototyping
what assistance classes should look like to make the whitelist
(eg systemd service files); also the packages will need to be
added to the package list for the initramfs image.
