Subject: Add S_IWUSR permission bit for O_CREAT

Add S_IWUSR permission bit for O_CREAT

In Ubuntu -haven't tested it elsewhere yet- gcc has a global cflag
called "D_FORTIFY_SOURCE=2" that errs when files are not created
with explicit user permissions. Since files are O_WRONLY, I added
the S_IWUSR permission bit.
