Subject: [PATCH] Misc FreeBSD fixes (#1926)

* helpers: drop incomplete GNU/kFreeBSD bits

Debian with FreeBSD kernel lacks Wayland-related packages and is not
officially supported since Jessie.

* KeybindManager: check VT ioctl availability instead of hardcoding

* plugins: add missing header for libc++ after 430778293e4c

src/plugins/PluginAPI.cpp:299:33: error: implicit instantiation of undefined template 'std::basic_istringstream<char>'
    std::istringstream          inStream(SYMBOLS);
                                ^
/usr/include/c++/v1/iosfwd:140:32: note: template is declared here
    class _LIBCPP_TEMPLATE_VIS basic_istringstream;
                               ^

* plugins: prefer llvm-nm with Clang after 430778293e4c

nm: invalid option -- j
