When testing if we should try to compact memory or drop caches before we
run the THP or HugeTLB tests we use | as an or operator. This doesn't work
since run_vmtests.sh is written in shell where this is used to pipe the
output of the first argument into the second. Instead use the shell's -o
operator.
