futex: Replace fshared and clockrt with combined flags

futex: Replace fshared and clockrt with combined flags

In the early days we passed the mmap sem around. That became the
"int fshared" with the fast gup improvements. Then we added
"int clockrt" in places. This patch unifies these options as "flags".
