unix: implement EpollCreate using EpollCreate1 on all linux platforms

Most newer architectures (e.g. arm64 or riscv64) don't provide the
epoll_create syscall. Some systems (e.g. Android) block it even if it
were available. In the kernel, the epoll_create syscall is implemented
[1] the same way EpollCreate is implemented in this package for
platforms without the epoll_create syscall. Thus, avoid the separate
wrapper and consistently implement EpollCreate using EpollCreate1.
