tools build: Fix the common set of features test wrt libopenssl

The recent introduction of the libopenssl feature test forgot to add the
-lssl to the test-all.o target, which made it always fail, fix it.

Noticed by looking at this file after building:

  $ cat /tmp/build/perf-tools/feature/test-all.make.output
  /usr/bin/ld: /tmp/ccBhO8WH.ltrans0.ltrans.o: in function `main':
  /home/acme/git/perf-tools/tools/build/feature/test-libopenssl.c:6:(.text.startup+0x2ed): undefined reference to `OPENSSL_init_ssl'
  collect2: error: ld returned 1 exit status
  $

It was added only to the individual ssl test, that works:

  $ cat /tmp/build/perf-tools/feature/test-libopenssl.make.output
  $ ldd /tmp/build/perf-tools/feature/test-libopenssl.bin | grep ssl
	libssl.so.3 => /usr/lib64/libssl.so.3 (0x00007fb81eda8000)
  $
