[PATCH] lib/bb/fetch2: don't skip checksums when local mirror enabled

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If you have PREMIRRORS set up to point to a local directory, the local
download function does nothing and always succeeds and the mirror code
was writing a .done stamp regardless, thus the checksum verification was
being skipped even if the file wasn't actually copied from the mirror.
