p5-Lexical-SealRequireHints: update to 0.011.

version 0.011; 2017-07-15

  * update test suite to not rely on . in @INC, which is no longer
    necessarily there from Perl 5.25.7

  * no longer include a Makefile.PL in the distribution

  * update op-munging code to the PERL_OP_PARENT-compatible style
    (though none of it is actually used on Perls new enough to support
    PERL_OP_PARENT)

  * rename internal gen_*_op() functions into a better style

  * consistently use THX_ prefix on internal function names
