ti-core-initramfs: Add TI_CORE_INITRAMFS_EXTRA_INSTALL

Add TI_CORE_INITRAMFS_EXTRA_INSTALL variable that another layer can use to
install additional packages/changes into the initramfs.  Setting this
variable will also turn on the initramfs even if the platform does not
have kernel modules to include.
