Fix a typo in the default module search path which are added to help implicit import when using explicit module build. Also added a default path that usually can find Darwin swift shim modules.
Note when turning on implicit clang module in swift requires disable relocatable PCM checks since the search path for implicit modules can pick up an incompatible module map that defines a module with the same name that was built explicitly. Make sure we don't apply base directory relocation for explicitly loaded modules.
