[PATCH] uki.bbclass: fix building of UKI images with multiple initramfs fstypes

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

If INITRAMFS_FSTYPES contains more than one entry, ukify build command
will fail as INITRD_ARCHIVE will contain extra strings. Use only the
first initramfs type, letting the user to specify other fstypes.
