copy-firmware: Always write Link: entries

File: entries in the WHENCE file overwrite existing files in the target
directory, however, Link: entries are skipped if the file exists in the
target directory. This can cause issues if the Link: entry is updated, but
the target directory contains an old symlink. Do not skip writing Link:
entries if the file exists, always create the symlink. This matches the
behavior of File: entries and ensures symlinks will contain values from
the WHENCE file.
