scripts/kernel-doc: parse kernel-doc deterministically



Regular expressions for highlights in kernel-doc are stored in a Perl
hash.  These hashes are ordered differently for each Perl run. This will
prevent kernel-doc to behave deterministically when parsing “@foo()” as
in some runs it will be interpreted as a parameter and in the others it
will be interpreted as a function.

We now sort the %highlights hash to get the same behavior on every run.
