usb: gadget: f_sdp: Provide filesize env variable for downloaded images
Currently it's not possible to get filesize of downloaded images and
it's impossible to automate some tasks in scripts. So this patch adds
`filesize` environment variable with size (as hex number in bytes) of
the last successfully downloaded file via `sdp` command.
