Bug#909480: Feersum FTBFS

[Xavier]

Control: severity -1 normal
Control: tags -1 + patch
Control: reassign -1 perl-modules-5.26

Sometimes, a closed connection isn't detected by HTTP::Tiny. To
reproduce the bug, use feersum sources:

$ perl Makefile.PL && make
$ taskset -c 0 perl -I blib/lib -I blib/arch t/63*

HTTP::Tiny tries to reuse a closed connection.

This little patch fixes the problem:
