Add support for wildcard in methods to permiss access to all methods
defined by the object. This can be usefull for process that run as
non-root user and needs to access ubus method.

After this gets some testing on master, can we please backport it to 
19.07 (and preferably also 18.06) ?

As usage of this (welcome!) feature increases, it would cause issues 
when backporting packages that adopt it, unless we also backport the 
feature itself...
