The scp download helper is broken when the server URL starts with 'scp://'.
Such prefix is used in two situations:
1. to let FOO_SITE point to an scp location without explicitly having to set
'FOO_SITE_METHOD = scp'
2. when BR2_PRIMARY_SITE or BR2_BACKUP_SITE points to an scp location. In
this case, there is no equivalent of 'SITE_METHOD'.
Strip out the scheme prefix, similarly to how the 'file' download helper
does it. That helper has the same cases as above.
