Fix RT [perl #72156] Re: Perl 5.12.0 RC 0 - Pager detection

Instruct ./getfile to trust the default pager value.  It might not begin
with a slash, or it might include some options, such as
"/usr/bin/less -R".  This patch copies the pager.U file from the
dist-3.5 directory, and then changes the 'fn=' line to trust the
default.
