tests/qtest/libqtest: Replace QTEST_TRACE with QTEST_QEMU_ARGS

Browse Source 
The QTEST_TRACE environment variable allows for any QEMU command line
option to be passed if used like so:

export QTEST_TRACE="-trace tracepoint -more -opts -here"

Formalize that usage by accepting a new QTEST_QEMU_ARGS
variable. Since the QTEST_TRACE now becomes redundant, remove its
usage.
