Always apply g:fuzzyy_files_exclude_{file,dir}

This makes sense to me, the defaults are now set to values that you
probably always want to ignore, vim swap files, tags files, common
version control directories, and users may want to always exclude some
files or directories without adding to gitignore or other ignore files.

For example, I might like to add tags.* to this, for Vim gutentags.
Sure, I could add to a "global" ignore file, but that won't necessarily
work with --no-ignore-parent, and maybe I want --no-ignore-parent. Also,
fd and rg don't follow include directives in git config, so if you set a
"global" gitignore using core.excludesFile from a config file included
from your global gitconfig it doesn't work as expected with fd and rg.
