win32: minor adjustments to file permissions

Mask the file permission bits in mingw_umask(), not when it's
called from run_applet_no_and_exit().

Rather than hardcode write permissions for group and other in
file_attr_to_st_mode() and mingw_fstat() make them respect the
current umask setting.

In mingw_fstat() there's no need to check the mode using S_ISDIR():
the hardcoded mode doesn't set S_IFDIR.  The compiler had already
figured this out so there's no reduction in bloat.
