pacman/util.c: support terminals with unknown width
Add detection for stdout being attached to a tty device. When this check fails, return a default width of 0, which callers interpret to mean "don't wrap". Conversely, when our term ioctl suceeds but returns 0, we interpret this to mean a tty with an unknown width (e.g., a serial console), in which case we default to a sane value of 80.
