[lldb][Windows] Fix TestLocateModuleCallback

[splhack]

Summary

D153735 added the tests but it is failing due to POSIX path vs Windows path.
https://lab.llvm.org/buildbot/#/builders/219/builds/4084

Fix it.

• MODULE_PLATFORM_PATH is POSIX path.
• Normalize self.input_dir, FileSpec and SymbolFileSpec fullpath.

LGTM. It should fix the buildbot failure.
