allow separate source and target files for applypatch

Allow applypatch to use different filenames for the source and target.
(Using the same filename is still fine; in fact the target filename
can be specified as "-" to mean "same as the source file.)  This will
allow us to still use diffs in the case of files being renamed, and
will allow us to use diffs for the boot and recovery images.
