The marker for PI futexes in the robust list is a hardcoded 0x1 which lacks any sensible form of documentation. Provide proper defines for the bit and the mask and fix up the usage sites. Thereby convert the boolean pi argument into a modifier argument, which allows new modifier bits to be trivially added and conveyed.
