build.info: implement PROGRAM_NO_INST, and dito for ENGINES, SCRIPTS, LIBS

PROGRAM_NO_INST, ENGINES_NO_INST, SCRIPTS_NO_INST and LIBS_NO_INST are
to be used to specify program, engines, scripts and libraries that are
not to be installed in the system.  Fuzzers, test programs, that sort
of things are of the _NO_INST type, for example.

For the benefit of build file templates and other templates that use
data from configdata.pm, a new hash table $unified_info{install} is
created.  It contains a set of subhashes, one for each type of
installable, each having an array of file names as values.  For
example, it can look like this:

    "install" =>
        {
            "engines" =>
                [
                    "engines/afalg/afalg",
                    "engines/capi",
                    "engines/dasync",
                    "engines/padlock",
                ],
            "libraries" =>
                [
                    "libcrypto",
                    "libssl",
                ],
            "programs" =>
                [
                    "apps/openssl",
                ],
            "scripts" =>
                [
                    "apps/CA.pl",
                    "apps/tsget",
                    "tools/c_rehash",
                ],
        },
