Make sure that the path to the Perl interpreter is correctly

adjusted under `make install' also for the printenv CGI script.

NOTICE: I still used INSTALL_DATA instead of INSTALL_SCRIPT because some of us
still thing we should install even these trivial shell scripts without execute
permissions. Even when we also have CGI's disabled in the default config.
What's the latest state? Should we change INSTALL_DATA to INSTALL_SCRIPT or is
double-paranoia really necessary?
