tests/e2e: Update github.com/creack/pty v1.1.7 -> v1.1.11

The fix is needed to mitigate consequences of
https://github.com/golang/go/issues/29458 "golang breaking change" that
causes following test failures on etcd end:

--- FAIL: TestCtlV2Set (0.00s)
    ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
--- FAIL: TestCtlV2SetQuorum (0.00s)
    ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
--- FAIL: TestCtlV2SetClientTLS (0.00s)
    ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
