[Patch] BaseTools: Fix a bug to correct SourceFileList

[Yonghong Zhu <yonghong.zhu@intel.com>]

We met a case that use two microcode files in the Microcode.inf file,
one is .mcb file, another is .txt file. then it cause build failure
because the SourceFileList include the .txt file's output file, while
this output file is still not be generated, so it cause
GetFileDependency report failure.
