Fix Encode(3p) loading module from incorrect relative path

This is upstream commit
https://github.com/Perl/perl5/commit/c1a937fef07c061600a0078f4cb53fe9c2136bb9

Quoting upstream:

Without this fix, Encode::ConfigLocal can be loaded from a path
relative to the current directory, because the || operator will
evaluate @inc in scalar context, putting an integer as the only
value in @inc.

Patch perl CVE-2016-1238

The problem relates to Perl 5 ("perl") loading modules from the
includes directory array ("@INC") in which the last element is the
current directory ("."). That means that, when "perl" wants to
load a module (during first compilation or during lazy loading of
a module in run-time), perl will look for the module in the current
directory at the end, since '.' is the last include directory in
its array of include directories to seek. The issue is with requiring
libraries that are in "." but are not otherwise installed.

The major problem with this behavior is that it unexpectedly puts
a user at risk whenever they execute any Perl scripts from a directory
that is writable by other accounts on the system. For instance, if
a user is logged in as root and changes directory into /tmp or an
account's home directory, it is possible to now run any shell
commands that are written in C, Python or Ruby without fear.

The same isn't true for any shell commands that are written in Perl,
since a significant proportion of Perl scripts will execute code
in the current working directory whenever they are run. For example,
if a user on a shared system creates the file /tmp/Pod/Perldoc/Toterm.pm,
and then I log in as root, change directory to /tmp, and run "perldoc
perlrun", it will execute the code they have placed in the file.
