[OE-core] [OE][jethro] Backport Perl Upgrade to 5.22.1

[Jens Rehsack]

Please backport the following from oe-core/master to jethro:

55a8df2056024acf714f47c85267c1eba8b7b6be
perl: Upgrade to 5.22.1

According to http://search.cpan.org/dist/perl-5.22.1/pod/perldelta.pod no incompatible changes but a lot of serious bugs fixed.

Cheers
