Title: [Runtime] Fix using uninitialized variable "is_valid_" for WGT package extracting.

The uninitialized variable "is_valid_" in package.cc(h) may lead to error when installing a WGT package, and it should be initialized in constructor.

Add a package type in Package class, hence the WGT and XPK have different extracting process, so need to add a flag to identify them.
