Here as well.

Hmm, so this test is just the same as umask02 but tries to create the
file as well.
What about we remove umask01.c and umask02.c and rename umask03.c to
umask01.c?
It's not like umask01.c or umask02.c adds any more value since umask03.c
is superset of these.

The test runs in unique temporary directory, there is no need for trying
to create unique filename.
