[program_options] Codecov failing on Travis CI for long time

Hi,

I've just submitted my first PR [1] to the library and Travis CI failed with:

+lcov --gcov-tool=gcov-7 --rc lcov_branch_coverage=1 --base-directory
/home/travis/build/boostorg/boost-root/libs/program_options
--directory /home/travis/build/boostorg/boost-root --capture
--output-file all.info
Capturing coverage data from /home/travis/build/boostorg/boost-root
Can't locate PerlIO/gzip.pm in @INC (you may need to install the
PerlIO::gzip module) (@INC contains: /etc/perl
/usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5
/usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18
/usr/local/lib/site_perl .) at /usr/local/bin/geninfo line 62.
BEGIN failed--compilation aborted at /usr/local/bin/geninfo line 62.
The command "ci/codecov.sh" exited with 2.

I see this failure has been happening for a year now affecting all PRs
from that period.
I think it's desirable to keep the CI-s green, especially if there is
no huge potential
of breaking it as the library has not seen much activity.

I can't offer a solution myself, but it may ring a bell to maintainer
or someone else who knows how to fix it.
