Prohibit usage of Test::Simple under 't/'

One of the objectives of t/porting/bootstrap.t has been to prohibit use of
testing modules which need to be loaded via 'use MODULE' in test files found
in subdirectories under 't/'.  In those subdirectories, we do not presume that
module loading via 'use MODULE' has been demonstrated to work.  However, the
unit test in bootstrap.t was written solely to spot instances of 'use
Test::More'.  It did not consider the possibility that a test file under 't/'
might 'use Test::Simple'.

There was one such test file which use-d Test::Simple:
t/lib/overload_nomethod.t.  This patch rewrites that file to use 't/test.pl'
(as other t/lib/*.t files customarily do) and adapts t/porting/bootstrap.t to
rule out 'use Test::Simple' as well as 'use Test::More' from '*.t' files
underneath 't/'.
