Fix 'canon' client interface

As per 1275 standard, canon converts the possibly ambiguous
device-specifier to a fully qualified pathname (see 6.3.2.2). It is kind
of find-alias for clients. Earlier canon implementation was not complete,
it was not at all returning the full path name. So grub was not getting
the alias path by calling canon and it was breaking.

In this patch I'm checking if the passed string is already a full path
by comparing the first character with '/'. In that case I return the
passed string as is. Otherwise I return the find-alias.

Get MAC address for client interface module

The network drivers ported to library get interfaced with net-snk
through client interface module. Hence the ci module should set
the MAC address during initialization.
