perf tools: Check libaudit availability for perf-trace builtin
The newly added trace command requires an external audit library.
However it can cause a build error because it's not checked whether the
libaudit is installed on system:
CC builtin-trace.o
builtin-trace.c:7:22: fatal error: libaudit.h: No such file or directory
compilation terminated.
make: *** [builtin-trace.o] Error 1
