Queued for review and testing, thank you! As usual, I could not resist
the urge to edit a bit, so please let me know if I messed anything up.
If there are too many of these, it might be easier for kvm.sh to switch
itself to EN-US mode, but this change both simplified the code and helped
defend the purity of the French language, so steady as she goes! ;-)
Thanx, Paul

commit 655f941b96cbfc6f8869142ece092d8617425948

tools/rcutorture: Make identify_qemu_vcpus() independent of local language
The rcutorture scripts' identify_qemu_vcpus() function expects `lscpu`
to have a "CPU: " line, for example:
CPU(s): 8
But different local language settings can give different results:
Processeur(s) : 8
As a result, identify_qemu_vcpus() may return an empty string, resulting
in the following warning (with the same local language settings):
kvm-test-1-run.sh: ligne 138 : test: : nombre entier attendu comme expression
This commit therefore changes identify_qemu_vcpus() to use getconf,
which produces local-language-independend output.
