[PATCH v7 1/9] bootimg_pcbios: seperate syslinux install into seperate functions

[Vincent Davis Jr <vince@underview.tech>]

Current oe-core bootimg_pcbios wic plugin only supports
booting with syslinux.

This commit seperates syslinux creation from
class BootimgPcbiosPlugin(SourcePlugin) override
functions in prepartion of supporting booting other
bootloaders in the wics plugin such as
	* grub
	* extlinux

Being moved now to make it easier to include
future bootloaders.
