[isar-cip-core][PATCH] swupdate-handler-roundrobin: Silence fetcher warnings with different SWUPDATE_BOOTLOADER

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

If SWUPDATE_BOOTLOADER is set to something else than efibootguard, e.g.
u-boot, we get warnings like this:

Unable to get checksum for swupdate-handler-roundrobin SRC_URI entry swupdate.handler.u-boot.ini: file could not be found

Our recipe only supports efibootguard, and downstream layers may not
even use it when a different bootloader is used. If downstream actually
wants to use out recipe and also provide some own swupdate.handler.ini,
it should rather override SWUPDATE_ROUND_ROBIN_HANDLER_CONFIG.
