syscall: implement EpollCreate using EpollCreate1 on all linux platforms
Most newer architectures (e.g. arm64, riscv64, loong64) 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. The epoll_create1 syscall is
available since Linux kernel 2.6.27 and the minimum required kernel
version is 2.6.32 since Go 1.18 (see #45964). Thus, avoid the separate
wrapper and consistently implement EpollCreate using EpollCreate1.
[1] https://elixir.bootlin.com/linux/v5.15-rc1/source/fs/eventpoll.c#L2006
The same change was already done in CL 349809 for golang.org/x/sys/unix.
For #45964
