strace-tst-thp.sh: Allow unsupported THP tests

Change strace-tst-thp.sh to

output=${test_prog}.$$
...
/bin/sh -c \
  "timeout -k 4 $((3*$TIMEOUTFACTOR)) ${cmd} --direct 2>&1" > "${output}"
if grep -E "madvise\(0x[0-9a-f]+, [0-9]+, 0xe)" "${output}"; then
...

so that unsupported THP tests exit with status 77.
