Don't generate texi2pod.pl, use it

This patch modifies texi2pod.pl to use #!/usr/bin/env perl instead of
#!/usr/bin/perl directly.  This approach works more many Python
scripts and is likely to be portable to all systems we care about.  If
someone knows of a Unix-like system still in use where this doesn't
work, please let me know.

(Another reason why this wasn't done before was that I didn't know,
and still don't know, of a way to change the executable of a file in
the CVS repository without having shell access to the repository.
With subversion it's as simple as `svn propset svn:executable ON
texi2pod.pl'.)

This simplifies doc/Makefile.in somewhat, which is always a good thing
in my book.

	* texi2pod.pl: Locate perl using the "env" program, so we don't
	need to modify texi2pod.

	* Makefile.in (wget.pod): Work with texi2pod.pl directly instead
	of generating it from texi2pod.pl.in.
