[PATCH] tester: Limit simultaneous QEMU jobs to 1

[Kinsey Moore]

There is an emulation problem between RTEMS and QEMU that causes several
sets of tests to fail in circumstances where there is high load on the
host machine. Running multiple instances of QEMU simultaneously
exacerbates this problem which includes all of the spintrcritical tests,
psx12, and some of the other sp* tests. Limiting QEMU to one job at a
time increases test duration, but minimizes the number of tests that
fail this way. This affects at least ARM and AArch64 emulation so those
testing environments have been targeted here.
