linux-user/syscall.c: add target-to-host mapping for epoll_create1()

Noticed by Barnabás Virágh as a python-3.7 failue on qemu-alpha.

The bug shows up on alpha as it's one of the targets where
EPOLL_CLOEXEC differs from other targets:
    sysdeps/unix/sysv/linux/alpha/bits/epoll.h: EPOLL_CLOEXEC  = 01000000
    sysdeps/unix/sysv/linux/bits/epoll.h:        EPOLL_CLOEXEC = 02000000
