This replaces the epoll_wait08 entry instead of adding epoll_wait09
alongside it. epoll_wait08 will be built but never run.

"That checks..." is a dangling clause; the body must stand alone as a
sentence (e.g. "Test that checks...").

Prefix typo: "syscall:" should be "syscalls:" (all other patches in
this series use "syscalls:").

Typo: "chcecks" -> "checks".

fds[] and efd are closed in run() but not reset to -1; cleanup() then
double-closes them on every run (TBROK). Reset each to -1 after
SAFE_CLOSE in run(), and use != -1 guards in cleanup() per LTP
convention.

Same double-close defect as epoll_wait11; apply the same fix.
