qtest: fix qtest log fd should be initialized before qtest chardev

qtest_log_fp should be inited before qemu_chr_add_handlers.
If not the log dumped from callback functions may be lost.

easy to reproduce it by command:
"QTEST_LOG=1 QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64
gtester -k --verbose -m=quick tests/qdev-monitor-test"

The log "[I xxxxxx] OPENED" should be printed out by
qtest_event, but does not.
