Subject: [PATCH] Fix link error with LLD 17

Developers of FreeBSD base system are currently working to upgrade its
LLVM/Clang/LLDB/LLD to 17. As a part of it they tried building all
ports in FreeBSD ports collections to check if build of them succeeds
with LLVM/Clang/LLD 17. As a result there are some ports that fail to
be built with it and unfortunately `security/clamav` is one of
them. The build of it fails with link error as following.

```
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'cli_cvdunpack' failed: symbol not defined
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'cli_dbgmsg_internal' failed: symbol not defined
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'init_domainlist' failed: symbol not defined
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'init_whitelist' failed: symbol not defined
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'cli_parse_add' failed: symbol not defined
  ld: error: version script assignment of 'CLAMAV_PRIVATE' to symbol 'cli_bytecode_context_clear' failed: symbol not defined
  cc: error: linker command failed with exit code 1 (use -v to see invocation)
```

According to the investigation of ClamAV's source code,
`cli_cvdunpack` is a static function so it isn't visible to external
consumers. And other mentioned symbols aren't found anywhere. So fix
link error by removing all of them from linker version script.
