perl: fix a regression with caller() not indicating the starting *.psgi program

In 2.0.1-41-g3480c30 I introduced a regression with how the top-level
stackframe would appear within Perl programs. Before we'd show the
filename of the *.psgi file, but after we just showed "-e".

We can retain the bugfix I added in 2.0.1-41-g3480c30 while having a
sensible stacktrace by overriding the file via the #line directive.

perl: add sanity checks to t/perl/test_input_with_offset.pl
perl: fix one-off error in 2.0-103-gf041d10 causing warnings in e.g. Plack::Request

This newly added support for read() offsets started causing "Use of
uninitialized value in subroutine entry" warnings.

This is all because there was a test for the number of items on the
stack, which ignored that the first argument is always the object, so 3
arguments to read() actually yields 4 arguments on the stack, not 3.

As a result we'd be calling SvIV() on a stack item that wasn't actually
passed in.
