openbmc工程化

优化fetch阶段文件下载速度
- 修改git下载方式，只下载指定commit,且depth为1
- 使用git全局代理加速下载
复用download文件
- 指定DL_DIR复用下载文件
复用native package
- 获取当前工程用到的package name list
#bitbike obmc-phosphor-image -g
- 获取native package
#cat pn-buildlist|grep -e "-native" -e "\-cross\-" > pn-native
- 只编译native package
#cat pn-native|xargs bitbake
- 编译完成后提取tmp/sysroot-component，未来此基线工程编译无需再反复编译native package
- 复用后可减少原native包源码+编译约8.3G空间
- 复用后可减少native包的任务处理时间,bitbake统计的任务耗时排序后截取最耗时的task如下，单位秒
