_modutils and _ip completion fixes

[Tomasz Pala <gotar@xxxxxxxxxx>]

Hello,

a little but irritating bug in Completion/Linux/Command/_modutils, around 110th line:

- s=( $modules_dir/$kver/(*~(source|build))/**/*.(o|ko|ko.gz|.ko.xz)(.:t:r:r) )
+ s=( $modules_dir/$kver/(*~(source|build))/**/*.(o|ko|ko.gz|ko.xz)(.:t:r:r) )


Additionally, attached patch for _ip completion, allowing one to use 'ip -c'
alias for ip command, as _regex_arguments stops processing on unknown argument
(with '?parse failed before current word?').

best regards,
