Makefile: regenerate perl/build/* if GIT-PERL-DEFINES changes

Change the logic to generate perl/build/* to regenerate those files if
GIT-PERL-DEFINES changes. This ensures that e.g. changing localedir
will result in correctly re-generated files.

I don't think that ever worked. The brokenness pre-dates my
20d2a30f8ff (Makefile: replace perl/Makefile.PL with simple make
rules, 2017-12-10).
