unix: don't fail TestPoll on EINTR from Poll

Occassionaly TestPoll fails on some builders due to Poll getting
interrupted:

--- FAIL: TestPoll (0.00s)
    syscall_unix_test.go:516: Poll: unexpected error: interrupted system call
FAIL
FAIL	golang.org/x/sys/unix	0.956s

Fix this by retrying Poll in case of EINTR, same as CL 207861 did in
TestSelect.
