Class name change for CLDRLocaleDataMetaInfo_jdk_localedata needs updating in makefile

When the generated class sun.util.resources.cldr.provider.CLDRLocaleDataMetaInfo_jdk_localedata changed names to sun.util.resources.cldr.provider.CLDRLocaleDataMetaInfo in JDK-8150434, the make target reference in GensrcCLDR.gmk was forgotten. The consequence of this is that the gensrc step is rerun at every build, causing the jdk.localedata module to also be compiled at every build.
