Enable Some "Oh My Zsh" Flags

1. `DISABLE_UNTRACKED_FILES_DIRTY` to disable marking untracked files under VCS
   as dirty.

2. Zsh completion need database-like files(.zcompdump-Johnson-PC-5.4.2), if
   "ZSH_DISABLE_COMPFIX" isn't set to "true", "Oh My Zsh" will check the
   security of the directory used to store these files, the directory isn't
   secure either group or others have write permission.
   Under WSL(Windows Subsystem for Linux) using directory of mounted Windows
   partition as home directory will cause Zsh completion complains the insecure
   directory issue.
   The completion dump file will regenerated when it is deleted, so the insecure
   directory checking is not very necessary.
