fs/ubi: add option to use custom ubinize config file

By default, the UBI FS target creates a ubinize configuration
file on-the-fly, for a single volume.  Add an option to specify
a custom config file.

E.g., one might want to deploy a system with a volume for the
built ubifs image, a volume for a future upgrade image, and a
volume for user data.

Select this option to use a custom ubinize configuration file,
rather than the default configuration used by Buildroot (which
defines a single dynamic volume marked as auto-resize). Passing
a custom ubinize configuration file allows you to create several
volumes, specify volume types, etc.
As a convenience, buildroot replaces the string
"BR2_ROOTFS_UBIFS_PATH" with the path to the built ubifs file.
So the volume defined for the root filesystem can specify the
image path as: image=BR2_ROOTFS_UBIFS_PATH
