[PATCH] wic: support passing extraargs for EFI partition creation

[Richa Bharti]

Some EFI firmwares require FAT filesystems to use specific geometry or
sector parameters.

Add support for an `extraargs` source parameter to allow passing
additional mkdosfs options when creating the EFI System Partition (ESP).
If no extra arguments are provided, mkdosfs defaults to "-S 512",
preserving existing behaviour.
