Change the Perl scripts to turn on lexical warnings instead of setting
the global $^W variable via the -w switch.
The -w sets warnings for all code that interpreter runs, while "use
warnings" is lexically scoped. The former is probably not what the
authors wanted.
As an auxiliary benefit it's now possible to build Git with:
PERL_PATH='/usr/bin/env perl'
Which would previously result in failures, since "#!/usr/bin/env perl -w"
doesn't work as a shebang.

This is a re-send, it's independent of bumping the version to 5.8 (use
warnings was introduced in 5.6), but a good idea anyway.
