perf data: Add doc when no conversion support compiled
This adds documentation on the environment variables needed to the
message telling that no conversion support is compiled in.
Committer testing:
$ make -C tools/perf install
$ perf data convert --all --to-ctf myctftrace
No conversion support compiled in. perf should be compiled with environment variables LIBBABELTRACE=1 and LIBBABELTRACE_DIR=/path/to/libbabeltrace/
