typing: switch an argument type to the generic form
This fixes the following pytype complaint:
File "/mnt/c/Users/Matt/hg/mercurial/commands.py", line 4672, in log: Function mercurial.logcmdutil.parseopts was called with the wrong arguments [wrong-arg-types]
Expected: (ui, pats: List[Union[bytearray, bytes, memoryview]], ...)
Actually passed: (ui, pats: tuple, ...)
