#138 ctags5.6 can\'t parse Ruby\'s anonymous class definition

[NARUSE, Yui]

ctags5.6 can't parse Ruby's singleton class
definition.

For example, if there is following script,

class << expression
end

We expect following result.

expression example.rb /^class <<
expression$/;" c

But ctags5.6 doesn't output anything.

This is because parseIdentifier in ruby.c returns
K_UNDEFINED,
when it find "<<" after "class" + SPs.
It doesn't parse SPs + "expression".

Anyway, a patch is below.
