Fix a Incremental build failure. The case is: Both A and B package will
include a same .h file, and in the driver's packages section, A
package is listed before B package, so we will use the .h file in the A
package and build success, then we directly delete the .h file in package
A, it cause increment build failure since in the AutoGenTimeStamp file
the .h file in A can't be found.
