Grepping for "CPU" on lscpu output isn't always successful, depending
on the local language setting. As a result, the build can be aborted
early with:
"make: the '-j' option requires a positive integer argument"
This commit therefore uses the human-language-independent approach
available via the getconf command, both in kvm-build.sh and in
kvm-remote.sh.
