wic: rawcopy: make source filenames unique
Rawcopy plugin copies source files to build folder before using them
to assemble result image. After assembling the image wic renames
source files to <image>.p<partition number>. If the same source file
is used in multiple partitions wic breaks trying to rename file that
doesn't exist.
Added <line number> suffix to the files when copying them to the
build dir. This should make filename unique even if the same source
file is used for multiple partitions.
