[Patch, Fortran] Set umask(0600) before calling mkstemp

Subject: [Patch, Fortran] Set umask(0600) before calling mkstemp

Depending on the system mkstemp might create the scratch files with 0666 permission (e.g. glibc <= 2.06); for security reasons, it should use 0600. Thus, one is supposed to set a umask before calling the function (see, e.g., the Linux man page for mkstemp).

Build and regtested on x86-64-linux.
OK for the trunk? Is this something one should back port to the branches?
