base.bbclass: add subversion-native to DEPENDS if there is svn:// in SRC_URI
* in some cases this could cause circual dependency (ie if we decide to
apr_svn.bb or something like that before subversion-native in dependency
tree), Saul said he had such case, but I wasn't able to reproduce it
here (here it builds subversion-native-1.7.0 fine).
