perf tools: Enable libtracefs dynamic linking
Currently libtracefs isn't used by perf, but there are potential
improvements by using it as identified Steven Rostedt's e-mail:
https://lore.kernel.org/lkml/20210610154759.1ef958f0@oasis.local.home/
This change is modelled on the dynamic libtraceevent patch by Michael
Petlan:

v3. Adds file missed in v1 and v2 spotted by Jiri Olsa.
