build: tweak the find modules even more

As described in https://github.com/yuzu-emu/yuzu/pull/9395#discussion_r1047456172 checking for PKG_CONFIG_FOUND before calling pkg_search_module() is unneeded, and some find modules (like FindFFmpeg.cmake) don't do this already. Consequently, this patch removes these checks.
