Subject: [PATCH] touch: Respect caller's umask

Currently, if the caller has a umask of 002 or 000, the file gets created as 644
anyway.

Also, add O_WRONLY to the open call, since POSIX says that "Applications shall
specify exactly one of the first five values (file access modes) below in the
value of oflag".
