PATCH: _cvs on zsh without dynamic-linking modules.

[Tanaka Akira <akr@jaist.ac.jp>]

I found a problem with _cvs on zsh without dynamic-linking modules.

Z:akr@is27e1u11% ../zz/bin/zsh.old -f
is27e1u11% bindkey -e; autoload -U compinit; compinit -D 
is27e1u11% cvs commit <TAB>
_cvs_extract_modifiedfile_entries:2: failed to load module: zsh/stat
is27e1u11% cvs commit 

This patch tries to detect zsh/stat module more carefuly.
