perl/Makefile.PL: detect MakeMaker versions incompatible with DESTDIR

Browse Source 
It appears that ExtUtils::MakeMaker versions older than 6.11 do not
implement the DESTDIR mechanism.  So add a test to the generated perl.mak
to detect when DESTDIR is used along with a too old ExtUtils::MakeMaker and
abort with a message suggesting the use of NO_PERL_MAKEMAKER.
