scripts: Add support for prepending path to file names

Added support for prepending path to file names in the final generated
u-boot script, for the use-case where we have the files in a separate
folder that can be accessed with a given $LOAD_CMD.

For example, we can have "fatload mmc 0:2" as LOAD_CMD but the
files would need to be loaded from the /boot folder within the 2nd
partition, not from the root ("/"). By specifying the "-p <path>"
parameter when running the script, paths like "/boot" can be
automatically prepended to the generated u-boot commands used
to load the files in board's memory.

Also added the support to disk_image script, to enable generating
a FAT partition with the binaries deployed in a custom folder
within it, if the "-p" parameter is specified.
