BUG/MINOR: cfgparse-global: fix allowed args number for setenv

Keywords setenv and presetenv take 2 arguments: variable name and value.
So, the total number, that should be passed to alertif_too_many_args is 2
("setenv <name> <value>") instead of 3. For alertif_too_many_args the first
argument index is 0.

This should be backported in all stable versions.
