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

[Naresh Bhat]

Remove the bootimg dependency as syslinux for aarch64. The reason to skip the syslinux package
- syslinux package contains x86 assembly code. Hence it cannot be compiled on aarch64.
- There is no BIOS on aarch64 to answer syscalls.
