Subject: Don't allow empty pathnames in fast-import

Don't allow empty pathnames in fast-import

riddochc on #git noticed corruption caused by import-tars.  This
was fixed in the prior commit by Dscho, but fast-import was wrong
to have allowed a tree to be created with an empty string as the
filename.  No operating system allows this, and Git itself doesn't
accept this into the index.
