Manman Ren e4a5d37d6b Modules: set SystemHeader to true if we are building a system module.
If we are processing a #include from a module build, we should treat it
as a system header if we're building a system module. Passing an optional
flag to HeaderSearch::LookupFile.

Before this, the testing case will crash when accessing a freed FileEntry.
