tools/lxterm/json: json file provide relative path, add json file directory to image names. 

Allow sharing same json file between serial boot and Ethernet/SDCard/SATAboot:

boot.json:
{
	"Image":        "0x40000000",
	"rv32.dtb":     "0x40ef0000",
	"rootfs.cpio":  "0x41000000",
	"opensbi.bin":  "0x40f00000"
}

If boot.json and images are located in images directory, using lxterm --images=images/boot.json
will now work.
