util: move checkosfilename call from path_auditor to opener

path_auditor is used for checking patterns too, but a pattern is not a valid
filename.

This patch fixes 98ee3dd5bab4, which introduced the bug:

  $ hg log -l3 glob:**.py
  abort: filename contains '*', which is reserved on Windows: mercurial\**.py
