tests: check path tracing of ppoll syscall
* tests/ppoll.c (main) [PATH_TRACING_FD]: Skip if /proc/self/fd/ is not available. Add a test call that use PATH_TRACING_FD. (main): Conditionalize expected output for those calls that do not use PATH_TRACING_FD with [!PATH_TRACING_FD]. * tests/ppoll-P.c: New file. * tests/pure_executables.list: Add ppoll-P. * tests/.gitignore: Likewise. * tests/gen_tests.in (ppoll-P): New entry.
