infeed: remove portability code for older versions of Solaris

Solaris 11 (at last!) defines optarg and optind in <unistd.h>,
which causes a gcc warning of redundant declarations.
Solaris 11 was released in 2011.

As optarg and optind are already used elsewhere without that
portability code that only innfeed has, just remove it.
