perf: add perf-feature for systemtap

Based on OE-Core rev: 8aafed5f4757550f2ff688e1b8981e5e8e6e3428 if systemtap
isn't disabled it's possible to race with systemtap headers being present
during autodetection and disappearing during the build:

    tests/sdt.c:14:21: fatal error: sys/sdt.h: No such file or directory
     #include <sys/sdt.h>
