[PATCH v2025.09.y 25/49] boards: qemu-virt: drop fitimage-pubkey.dts

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

CONFIG_BOOTM_FITIMAGE_PUBKEY was removed in v2025.09.0 and the device
tree snippet that we merged at runtime into the DT we receive from QEMU
is now empty and no longer serves a purpose.

Remove it as it's actually detrimental: of_merge_nodes is a low-level
operation that doesn't handle duplicate nodes and when
CONFIG_EXTERNAL_DTS_FRAGMENTS adds a state node of its own, the barebox
barebox live device tree ends up with the state twice.
