[OE-core] [OE-core v1 PATCH 2/5] syslinux: Remove bootimg dependency for aarch64

[Naresh Bhat]

Remove the bootimg dependency as syslinux for aarch64. The reasons to skip the syslinux package
- syslinux package contains x86 assembly code. Hence compilation errors on aarch64.
- There is no BIOS on aarch64 to answer syscalls.
