bitbake/fetch2: When replacing URLs in mirror handling mask out empty entries

The symptom of this problem is something like a cvs url which specifies
a username where the username is then passed through to something like
an http mirror.

This patch fixes things by ensuring empty entries are preserved in the
new URL.
