[Fix] nvm_alias: unset zsh's extendedglob while reading an alias file

`#` is a repetition operator under `extendedglob`, so `${VAR%%#*}` is an invalid pattern: zsh aborts the expansion and `nvm_alias` silently prints nothing, leaving the `default` alias unresolved when nvm.sh is sourced. The read loop moves into `nvm_print_alias_file` so that `local_options` scopes the option change to that section alone, rather than to everything `nvm_alias` does, and restores whatever the caller had set.

[Fix] zsh: restore nomatch and markdirs rather than clobbering them
