PATCH: completion for a couple more builtins

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This patch adds _arguments based completion for alias and jobs.
Unfortunately, _jobs already exists for completing jobs so I've had to
use the name _jobs_builtin. I'm happy to rename this if anyone can think
of a better name. These were the only builtins I identified as using an
existing completion but needing a proper one using _arguments.

To summarise, remaining builtins lacking a proper completion are:

pushln, getln, limit, unlimit, unset - possibly should be done
exit, bye, logout, return - should we use the _message completion
suggested?
echoti - if we sort out ${(k)terminfo} this would be easy
[, test - should we use the _message suggestion directing users to
[[..]]?
echo, pwd - easy if we ignore the possibility that it is echo/pwd from
/bin
dirs, suspend, zprof, unalias - only take one option which makes it a
bit pointless
break, continue, comp*, zformat, zparseopts, zregexparse - not useful
interactively
umask - would just be _message so a bit pointless
_typeset should possibly handle autoload and functions
there is also the cap and clone modules but I never use them so am not
sure what they should be.
