xlat/gen.sh: speedup xlat generation
This commit implements the following changes:
- increases the number of concurrent jobs to twice the CPU count;
- creates a circular buffer, so instead of running multiple jobs
at once, the generator tries to keep about the same number of jobs
being run concurrently;
- runs gen_git and gen_make concurrently in order to squeeze in
one more bit of concurrency.
With my deeply scientific measurements, this approach achieves
up to 15% speedup with dash and about 30-40% with bash as /bin/sh
on a 4-core machine.

run job to it; increase the limit of jobs to ncpus * 2; when the limit
is reached, wait for the first pid in pids instead of resetting jobs

into background.
