[lit, pdb] Fix func-symbols.test (on Windows)
[lit, pdb] Fix func-symbols.test (on Windows)

Summary: This test was failing sporadically on windows because the order in which the symbols are generated was different between builds. To fix the test, we need to run FileCheck twice - once for each set of symbols we want to verify. The test only runs on Windows.
