qemu-char: simplify pty polling
There is no need to use a timer and pty_chr_read to detect a connected
pty. It is simpler to just call g_poll periodically and check for POLLHUP.
It is done once per second, and only if the pty is disconnected, so it
is cheap enough.
Tested with "-monitor pty" and "-serial mon:pty", both of which work
correctly and do not freeze QEMU. (How to test ptys? "socat -,raw,echo=0
/dev/pts/4,raw").
