stop word splitting from leaking out of setup-env (#14472)

Browse Source 
The pathadd function was using setopt to configure zsh for word
splitting, which leaks out of the function and breaks default
functionality in a number of external zsh plugins and packages.  This
switches to emulate -L, just as the spack function uses, to keep the
setting local to the function.
