One of this fetch2 patches break https?:// in MIRRORS

It's used e.g in openembedded-core/meta/classes/mirrors.bbclass:
https?$://.*/.* http://downloads.yoctoproject.org/mirror/sources/
https?$://.*/.* http://sources.openembedded.org/

I've tested it with older bitbake in PREMIRRORS (to make log.do_fetch
log shorter) on libcap (which doesn't exist on upstream URL).
