test: drop the trailing whitespace from the QEMU version check

I suspect the original version of the regex was written on a system,
which prints both the QEMU version and the QEMU package version in the
--version output, like Fedora:

$ /bin/qemu-system-x86_64 --version
QEMU emulator version 4.2.1 (qemu-4.2.1-1.fc32)

However, Arch Linux prints only the QEMU version:
$ /bin/qemu-system-x86_64 --version
QEMU emulator version 5.2.0
Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers

This causes the awk regex to not match the version string, since there's
no whitespace after it, causing the version check to fail (as well as the
TEST-36-NUMAPOLICY) as well.

Follow-up for 43b49470d1f2808555c07f64cd0a1529b7ddd559.
