[GIT PULL] syscall: update io_uring_enter2() signature

[calebsander]

Since kernel 5.11, io_uring_enter2() accepts a IORING_ENTER_EXT_ARG flag allowing a struct io_uring_getevents_arg * to be passed in place of the sigset_t * argument. Kernel 6.12 adds the IORING_ENTER_EXT_ARG_REG flag, which interprets the argument as an offset into a region of struct io_uring_reg_wait's registered with IORING_REGISTER_CQWAIT_REG.

Kernel 5.11 was released over 4 years ago, so it seems more accurate for the argument type to be a void * rather than a sigset_t *. Change the argument type and rename it from "sig" to "arg" to match the man page. Using void * removes the need for a confusing pointer cast for callers passing struct io_uring_getevents_arg *.
