perf list: Use relative path for tracepoint scan

Browse source

Committer notes:

Added missing #include <unistd.h> for the close() prototype to fix this
on Alma Linux 8:

   1    21.54 almalinux:8                   : FAIL gcc version 8.5.0 20210514 (Red Hat 8.5.0-16) (GCC)
    util/print-events.c: In function 'print_tracepoint_events':
    util/print-events.c:103:4: error: implicit declaration of function 'close'; did you mean 'clone'? [-Werror=implicit-function-declaration]
        close(evt_fd);
        ^~~~~
        clone

Also use the newly added scandirat feature test to check if that
function is available, providing a HAVE_SCANDIRAT_SUPPORT conditional
warning to the user if it isn't available.
