qtest: use synchronous I/O for char device
Peter reported that rtc-test would periodically hang. It turns out
this was due to an EAGAIN occurring on qemu_chr_fe_write.
Instead of heavily refactoring qtest, just use a synchronous version
of the write operation for qemu_chr_fe_write to address this problem.
