Cygwin: device_access_denied: return false if O_PATH is set
If O_PATH is set in the flags argument of
fhandler_base::device_access_denied, return false. No
read/write/execute access should be required in this case.
Previously, the call to device_access_denied in open(2) would lead to
an attempt to open the file with read access even if the O_PATH flag
was set.
