bitbake: ast: Fix support for anonymous methods in wildcard .bbappend files

When using wildcard .bbappend files with anonymous methods in them,
bitbake/python fails to parse the generated code since the '%' is encoded
in the generated method name.

Fix this by including '%' in the convert-to-underscore list during
method name mangling.

While we're at it, move the method name mangling translation table
to a class variable, as suggested by Chris Larson.
