Benjamin Berg f82a9e7b9f um: fix execve stub execution on old host OSs ... The stub execution uses the somewhat new close_range and execveat syscalls. Of these two, the execveat call is essential, but the close_range call is more about stub process hygiene rather than safety (and its result is ignored). Replace both calls with a raw syscall as older machines might not have a recent enough kernel for close_range (with CLOSE_RANGE_CLOEXEC) or a libc that does not yet expose both of the syscalls.
