classes/distrodata: split SRC_URI properly before determining type
We weren't splitting SRC_URI values containing multiple URIs here; this
didn't cause any errors except when a trailing ; was left on a URI, in
which case the next URI was considered part of the parameter, which
didn't contain a = and therefore was considered invalid.
We only care about the first URI in SRC_URI in this context (since
that's the upstream URI by convention) so split it as we should and take
the first item.
Fixes [YOCTO #8645].
