[meta-virtualization] [PATCH] protobuf-c: Add protobuf's pkgconfig path into PKG_CONFIG_PATH

[jianchuan.wang at windriver.com]

From: Jianchuan Wang <jianchuan.wang at windriver.com>

Add the protobuf's pkgconfig path into PKG_CONFIG_PATH
so that pkg-config can find the protoc from sysroot in the configure process.
And don't conflict even if installing the protobuf in the localhost.
