[PATCH] bitbake/fetch2: Improve stamp creation in mirror code

[Richard Purdie]

Under certain conditions such as local file:// mirrors of all files,
bitbake might not check checksums. This is not desirable and we should
always check the checksum where possible.
    
This only exception to this is the git mirror tarball case where the
checksum is unknown but we need to create the .done stamp for other
reasons. This patch preserves thta functionality but in a more specific
section of code where this doesn't interfere in normal checksums.
