Fix FindRepository matching for KTS with type information

Replace MethodMatcher-based pluginManagement/buildscript detection with
simple name matching, since the synthetic class names (RewriteSettings,
RewriteGradleProject) don't match the real types resolved by the K2
compiler (org.gradle.api.initialization.Settings, org.gradle.api.Project).
