We may get the error on some hosts when build in deeper dir:
/bin/sh: /path/to/tmp/sysroots/i686-linux/usr/bin/perl-native/pod2man: /path/to/tmp/sysroots/i686-li:
bad interpreter: No such file or directory

Note the "i686-li", it should be "i686-linux", but is truncated by the host.

We can use "/usr/bin/env nativeperl" as we have done in cpan.bbclass for other recipe's perl script to fix the problem.

Fixed:
- There might be a space between "#!" and "/pat/to/usr/bin/perl", e.g.:
"#! /usr/bin/perl", now also matches it.

- There might be the lines like the following in the body:
eval 'exec /path/to/usr/bin/perl-native/perl -S $0 ${1+"$@"}'

Now we only check "#! */path/to/usr/bin/perl" to make sure it is a perl script, but match and fix the lines in both header and body.
