unix: fix assertion failure when the signal pipe overflows

An incorrect assert() statement was causing libuv to crash when writing to an internal signal pipe would result in EAGAIN/EWOULDBLOCK. This commit doesn't solve the underlying issue that the signal pipe can overflow. This should fix nodejs/node-v0.x-archive#5538
