tools/test-runner: replace alloca() based argv setup
Rewrite alloca() based argv array construction that required manual size
counting with vasprintf string array. This allows splitting start_qemu()
to multiple functions.

tools/test-runner: use virtiofsd for filesystem passthrough
The 9p mount passthrough I/O is fairly CPU hungry and slow. This matters
for e.g. running Python in test-runner, since it has to read some amount
of files for startup.
Add support for virtio-fs, which is significantly less CPU intensive.
Enable it by default if /usr/libexec/virtiofsd is available, fall back
to 9p if virtiofsd not usable.

tools/test-runner: Fix CPUID register clobbers
CPUID modifies EAX, EBX, ECX and EDX, but the inline asm clobber list is
incomplete. Use the __get_cpuid() intrinsic instead.
Fixes rootfs_setup(r, argv) crashing due to impossible r != &rootfs due
to clobbered registers.
