completion: use native ZSH array pattern matching

When clearing the builtin operations on re-sourcing in the ZSH case we
can use the native ${parameters} associative array keys values to get
the currently `__gitcomp_builtin_*` operations using pattern matching
instead of using sed.

As also stated in commit 94408dc7, introducing this change the usage of
sed has some overhead implications, while ZSH can do this check just
using its native syntax.
