tools feature: Add missing -lzstd to the fast path feature detection

Browse source 
We were failing that due to GTK2+ and then for the ZSTD test, which made
test-all.c, the fast path feature detection file to fail and thus
trigger building all of the feature tests, slowing down the test.

Eventually the ZSTD test would be built and would succeed, since it had
the needed -lzstd, avoiding:

  $ cat /tmp/build/perf/feature/test-all.make.output
  /usr/bin/ld: /tmp/ccRRJQ4u.o: in function `main_test_libzstd':
  /home/acme/git/perf/tools/build/feature/test-libzstd.c:8: undefined reference to `ZSTD_createCStream'
  /usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libzstd.c:9: undefined reference to `ZSTD_freeCStream'
  collect2: error: ld returned 1 exit status
  $

Fix it by adding -lzstd to the test-all target.

Now I need an entry to 'perf test' to make sure that
/tmp/build/perf/feature/test-all.make.output is empty...

Fixes: 3b1c5d9659 ("tools build: Implement libzstd feature check, LIBZSTD_DIR and NO_LIBZSTD defines")
