gVisor bot 9bad87339a Better strace logging for epoll syscalls. 
Example:

epoll_ctl(0x3 anon_inode:[eventpoll], EPOLL_CTL_ADD, 0x6 anon_inode:[eventfd], 0x7efe2fd92a80 {events=EPOLLIN|EPOLLOUT data=0x10203040506070a}) = 0x0 (4.411µs)

epoll_wait(0x3 anon_inode:[eventpoll], 0x7efe2fd92b50 {{events=EPOLLOUT data=0x102030405060708}{events=EPOLLOUT data=0x102030405060708}{events=EPOLLOUT data=0x102030405060708}}, 0x3, 0xffffffff) = 0x3 (29.891µs)

Michael Pratt 76483b8b1e Check sigsetsize in rt_sigaction 
This isn't in the libc wrapper, but it is in the syscall itself.

Discovered by @xiaobo55x in #1625.
