blacklist patch

Proposed patch to add a warning if blacklisted. Effect:

$ stap -e 'probe kernel.function("do_symlink") { next }'
WARNING: function do_symlink is in blacklisted section: keyword at <input>:1:1
 source: probe kernel.function("do_symlink") { next }
         ^
semantic error: while resolving probe point: identifier 'kernel' at :1:7
        source: probe kernel.function("do_symlink") { next }
                      ^

semantic error: no match (similar functions: do_symlink, add_symlink,
del_symlink, do_setlink, SyS_symlink)
Pass 2: analysis failed.  [man error::pass2]
