  test: fix test for non-installed testing

On a system without DTrace installed, <sys/usdt.h> cannot be found,
causing this test to fail.  Use test_cppflags to ensure the correct
location is used in all cases.

  test: Adapt USDT PC search for USDT LTO changes

To check USDT PCs, we looked at disassembly for characteristics that
indicated USDT probes.

With LTO, however, USDT instrumentation has changed.

Therefore, use showUSDT in tst.pidprobes.sh to extract USDT PCs.

Note that tst.pidargs.sh and tst.pidargmap.sh depend on
tst.pidprobes.sh.  Therefore, those tests also benefit from this change.
They do not yet pass, however, since index 0 for args[] is said to be
out of range.
