Subject: [PATCH] Fixes: 659ecd038818 plugins: percol: Check for alias zz
 before unalias

The original patch (659ecd038818c1b27bddaa2e60b0eb7f044f644a)
unaliases the percol alias, however, does not validate if the alias
is already defined. This leads to the following message that is shown
everytime a new bash session is spawned where this variable is not
defined when the percol plugin is enabled.

bash: unalias: zz: not found
