Makefile: generate Perl header from template file
Currently, the generated Perl script headers are emitted by commands in the Makefile. This mechanism restricts options to introduce alternative header content, needed by Perl runtime prefix support, and obscures the origin of the Perl script header. Change the Makefile to generate a header by processing a template file and move the header content into the "perl/" subdirectory. The generated header content will now be stored in the "GIT-PERL-HEADER" file. This allows the content of the Perl header to be controlled by changing the path of the template in the Makefile.
