bitbake/fetch2: Drop old md5 handling code

Drop some old md5 functions since we have improved functionality now which includes
sha256 checksum support. This stops each download being md5 checksumed twice.

Also change ".md5" stamp extentions to ".done" to better describe its use as a
download complete marker file and no longer write the md5 sum to the files.
