perf tests shell: Skip trace+probe_vfs_getname.sh if built without trace support

If perf was built without trace support, the trace+probe_vfs_getname.sh
'perf test' entry fails:

# perf trace -h
perf: 'trace' is not a perf-command. See 'perf --help'

# perf test 64
64: Check open filename arg using perf trace + vfs_getname: FAILED!

Check trace support, so that we'll skip the test in that case:

# perf test 64
64: Check open filename arg using perf trace + vfs_getname: Skip
