zsh_completion: use revsets to exclude this rev from suggestions to hg merge
One of the most important aspects of a completion system is its speed, so 1
call to hg is definitely better than 4.
Sorting by rev (descending) is to preserve the same order as in `hg heads`
output.
While at it, declare branches as an array too.
