EmbeddedPkg/Ebl: Move the flag string %a for the path from the PCD to the function call

The UEFI platform designer had to add '%a' to their EBL prompt PCD to print out the path
in the shell.
This change makes the addition of the path automatically after the platform specific value
in the EBL shell.
