Update: Add umask integer to fll_program_data_t.

This should be a standard practice that ideally must go away if the POSIX standard ever fixes that idiotic umask() design.
Never under any circumstances should a read-only operation result require a write operation!
I am forced to work around this, so I might as well provide a standard practice work-around.
