Fix a regression in 499c29394ce (Makefile: allow building without
perl, 2009-04-03) where we'd stop cleaning the perl/* directory
because NO_PERL was defined, thus leaving behind litter if the flag at
"clean" time didn't match that of build time.

In 499c29394ce this was done to avoid relying on the perl/Makefile.PL,
but since my 20d2a30f8ff (Makefile: replace perl/Makefile.PL with
simple make rules, 2017-12-10) we can clean things in that directory
unconditionally.
