Log Message:
This previously didn't patch to stop installing the gzip.info file
because it was just removed after.

But now use a patch to disable the install and disable the
creation of the ${PREFIX}/info directory.
(${PREFIX}/info is wrong; pkgsrc uses ${PREFIX}/${INFO_DIR}.)

(The patch also includes the BSD_INSTALL_SCRIPT change
which was previously done in the Makefile using sed.)
