[PATCH] _git: Use associative array for third-party completion

[Aaron Schrab <aaron@xxxxxxxxxx>]

When loading completion for third-party git commands use an associative
array to track if something has been loaded rather than a normal array.

I started looking into this after I added a `_git-f` file to my function
path while having `$f` defined as a variable I started getting `bad math
expression: operand expected` the first time I used git completion. The
line number referenced by that error pointed at where this was
apparently trying to see if there was already an entry in
`$_git_third_party_commands`. Unless I'm completely missing something
that wouldn't work as it was written. Since this section of the code is
trying to keep track of command names and an associated description an
associative array seems like a much better option. When later copying
this into `$third_party_commands` I've left that as a normal array.
