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

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 3b1c5d9659718263 ("tools build: Implement libzstd feature check, LIBZSTD_DIR and NO_LIBZSTD defines")
