[PATCH] fixes for ActiveState Perl

The make for perl is now retrieved from Perl's config. The make fragment in perl/Makefile.PL added in MY::postamble is disabled on Win32, as it relies on GNU make syntax, and Win32 users are not likely to have an ancient EU::MM version.

A Windows path for PERL_PATH is now supported as well, e.g.: make PERL_PATH=C:\\Perl\\bin\\perl or from cmd.exe: make PERL_PATH=C:\Perl\bin\perl .

t9700-perl-git.sh now passes on ActiveState Perl. Some tweaks were necessary in
Git.pm: a more correct check for absolute directory, exit code check on closing
the "pipe", and always closing the cat_blob bidirectional pipe (with errors
 ignored) so as not to leave zombie processes. The waitpid call on closing the
bidirectional pipe is now timed and the process is killed if necessary. Also
added some binmode calls to t/t9700/test.pl to make the blob tests pass.
