scripts: Switch to more portable Perl shebang

The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.

This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.

This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

KEYS: Provide a script to extract a module signature

The supplied script takes a signed module file and extracts the tailmost
signature (there could theoretically be more than one) and dumps all or
part of it or the unsigned file to stdout.

Call as:

	scripts/extract-module-sig.pl -[0adnks] module-file >out

where the initial flag indicates which bit of the signed file you want dumping
to stdout:

 (*) "-0".  Dumps the unsigned data with the signature stripped.

 (*) "-a".  Dumps all of the signature data, including the magic number.

 (*) "-d".  Dumps the signature information block as a sequence of decimal
     	    numbers in text form with spaces between (crypto algorithm type,
     	    hash type, identifier type, signer's name length, key identifier
     	    length and signature length).

 (*) "-n".  Dumps the signer's name contents.

 (*) "-k".  Dumps the key identifier contents.

 (*) "-s".  Dumps the cryptographic signature contents.

In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will
print a warning to stderr and dump nothing to stdout, but will otherwise
complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d"
will show "0 0 2 0 0 <pkcs#7-msg-len>".
