bootimg_pcbios: move syslinux install into seperate functions

Current oe-core bootimg_pcbios wics plugin
only supports installing syslinux directly
into the resulting wic image.

This commit seperates syslinux installation from
class BootimgPcbiosPlugin(SourcePlugin) override
functions in preparation of supporting the installation
of other bootloaders to the resulting wics plugin
such as:
	* grub
	* extlinux

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