Update p5-Lexical-SealRequireHints from version 0.002 to version 0.003.

Upstream changes:
version 0.003; 2010-04-10

  * bugfix: in pure-Perl implementation, make sure ambient package (from
    which require is invoked) is passed on correctly to the code in the
    required file, on those Perls where it is so inherited

  * in XS, use macros to avoid explicit passing of aTHX, in the manner
    of the core

  * in XS, avoid using "class" as a variable name, for compatibility
    with C++ compilers

  * make all numeric comparisons against $] stringify it first, to avoid
    architecture-dependent problems with floating point rounding giving
    it an unexpected numeric value

  * in Build.PL, explicitly declare configure-time requirements

  * add MYMETA.yml to .cvsignore
