Patch with fix

I tried to update perl-Syntax-Highlight-Engine-Kate to version 0.09, but it
failed with following error

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0,
'inc', 'blib/lib', 'blib/arch')" t/*.t

The source of the issue is old version of perl-ExtUtils-MakeMaker, which allows
to set default switches (e.g. -w) in Test::Harness.
It was fixed at version 6.77_7

    do not set default switches in Test::Harness; not even -w


New test command generated by updated EU::MM passed.

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-MTest::Harness"
"-e" "undef *Test::Harness::Switches; test_harness(0, 'inc', 'blib/lib',
'blib/arch')" t/02-perl.t
t/02-perl.t .. ok   
All tests successful.


Fedora 19 is also affected.

The patch works for both (F19 and F20).
