[LTP] [PATCH] syscalls/epoll_ctl04: add ELOOP to expected errnos

[Jan Stancek]

Kernel commit f2e467a48287 ("eventpoll: Fix semi-unbounded recursion")
added an extra checks for determining the maximum depth of an upwards walk,
which startign with 6.17-rc kernels now hits ELOOP before EINVAL.

Add ELOOP to list of expected errnos.
